QUES 2. What is the area of the largest triangle that can be fitted into a rectangle of length ‘l’ units and width ‘w’ units?

a) lw/3

b) 2lw/3

c) 3lw/4

d) lw/2

Solution:

The triangle which has its base as the length of the rectangle and its height as the width of the rectangle is the largest triangle that can be fitted in the triangle.

Alternatively, the triangle which has its base as the width of the rectangle and its height as the length of the rectangle will be the largest triangle that can be fitted in the rectangle.

The area computed in both the instances will be same.

If the base of the triangle is ‘l’ and its height ‘w’, then its area is  lw2

A. 110
B. 170
C. 511
D. 181

Sol: Option C
15 * 2 + 1 = 31
31 * 2 +1 = 63
63 * 2 + 1= 127
127 * 2 + 1= 255
255 * 2 + 1 = 511

QUES 6.  In a certain school, 20% of students are below 8 years of age. The number of students above 8 years of age is 2/3 of the number of students of 8 years of age which is 48. What is the total number of students in the school?

A. 72
B. 80
C. 120
D. 150
E. 100

Explanation: Let the number of students be x.

Then, Number of students above 8 years of age = (100 – 20)% of x = 80% of x.

80% of x = 48 + 2/3 of 48

80/100x = 80

x = 100

7. If the price of petrol increases by 25% and Raj intends to spend only an additional 15% on petrol, by how much % will he reduce the quantity of petrol purchased?

a)10%

b)12%

c)8%

d)6.67%

e)12.5%

8%. Choice (c)

Let the price of 1 litre of petrol be Rs.x and let Raj initially buy ‘y’ litres of petrol.
Therefore, he would have spent Rs. xy on petrol.

When the price of petrol increases by 25%, the new price per litre of petrol is 1.25x.

Raj intends to increase the amount he spends on petrol by 15%.
i.e., he is willing to spend xy + 15% of xy = 1.15xy

Let the new quantity of petrol that he can get be ‘q’.
Then, 1.25x * q = 1.15xy
Or q = = 0.92y.

As the new quantity that he can buy is 0.92y, he gets 0.08y lesser than what he used to get earlier.
Or a reduction of 8%.

QUES 8. A bus travels at 54km/h while moving but after accounting for stopping time, to let passengers on and off the coach, it averages a speed of 45km/h. How many minutes does the bus stop for each hour?

In one hour without stopping, the bus would have travelled 54km. Once stopping is factored in, the bus actually travels 45km. So it travels 9km less far as a consequence.

Distance/Speed = Time

9km/54kmph = 0.16 hours

0.16 x 60 = 10 minutes

So the bus stops for ten minutes in every hour on average.

QUES 9.A merchant marks his goods up by 60% and then offers a discount on the marked price. If the final selling price after the discount results in the merchant making no profit or loss, what was the percentage discount offered by the merchant?

a)60%

b)40%

c)37.5%

d)39%

Depends on the cost price

Correct Answer – 37.5% discount. Choice (3)

Assume the cost price to be 100.
Therefore, the merchant’s marked price will be 100 + 60% of 100 = 160

Now, the merchant offers a discount on the marked price. The discount results in the merchant selling the article at no profit or loss or at the cost price.

That is the merchant has sold the article at 100.

Therefore, the discount offered = 60.

Discount offered is usually measured as a percentage of the marked price.

Hence, % discount = QUES 10A Women’s Age Is 120% Of What It Was 15 Years Ago,But  75 % Of What It Will Be After 15 Years.What Is Her Present Age?

a60

b)55

c)65

d)45

Let us Consider the present age be x years.Then,

15 years ago:

(x-15)

Given that the age of the women is 120% of what it was 15 years ago.

Therefore Present age

120% of (x-15)

After 15 years:

Women;s Age will be (x+15)

Given that the age of the women is 75% of what it was after 15 years.

75% of (x+15)

To Find the Present age let us equate the two equation,

120% of (x-15)=75% of (x+15)

120/100 (x-15)=75/100 (x+15)

6/5(x-15)=3/4(x+15)

6*4*(x-15)=3*5*(x+15)

24(x-15)=15(x+15)

24x-360=15x+225

9x=585

x=65

QUES 11.  If x3 + y3 = 9 and x + y = 3, then the value of x4+y4 is,
(a) 21
(b) 0
(c) 17
(d) 25

Explanation:

x3+y3 = (x + y) × (x2 − xy + y2)

Putting given values of x3+y3 and (x + y)
9 = 3 × ((x+y)2 − 3xy)
= 3 × (9 − 3xy)
= 27 − 9xy

9xy = 18
xy = 2

x4 + y4 = (x2 + y2)2 - 2x2y2
= (x2 + y2)2 - 2*4
[Putting value of xy]
= ((x + y)2 - 2xy)2 - 2*4
[Putting values of (x+y) and xy]
= (9 - 4)2 - 2*4
= 17

QUES 12. A man invests Rs.5000 for 3 years at 5% p.a. compound interest reckoned yearly. Income tax at the rate of 20% on the interest earned is deducted at the end of each year. Find the amount at the end of the third year.

(a) 5624.32

(b) 5630.50

(c) 5788.125

(d) 5627.20

Solution:

5% is the rate of interest. 20% of the interest amount is paid as tax. That is 80% of the interest amount stays back. Therefore, if we compute the rate of interest as 80% of 5% = 4% p.a., we will get the same value.

The interest accrued for 3 years in compound interest = 3*simple interest on principal + 3*interest on simple interest + 1*interest on interest on interest. = 3*(200) + 3*(8) + 1*0.32 = 600 + 24 + 0.32 = 624.32

The amount at the end of 3 years = 5000 + 624.32 = 5624.32 • Total Number of questions : 7 Ques
