Sample TCS Ion CCQT Quantitive Aptitude Questions Answers

Ques 1. Amina sells a TV at a profit of 25%. Had she sold it at a profit of 25% of the selling price, her profit would have increased by 5% of the cost price plus Rs. 150. What is the cost price of the TV?

1. 13000
2. 12480
3. 12000
4. 10800

Ans: Let CP= x Profit in 1st care = x*25/100 = (¼)x

(¼)x = x* (s/100) + 150 = 12000

Ques 2. Amina marks the price of an article 40% above the cost price. If she changes the discount from 5% to 10%, the profit would decrease by Rs. 14. How much profit would she earn, if she gives a discount of 20% on the marked price?

1. 32
2. 34
3. 30
4. 24

Ans: Let CP = 100, MP=140

Diff. between profit sold at 5% and 10% = (140*5/100) = 7

When diff = 7, then CP = 100

14———–100*14/7 = 200 =MP

Discount = 20%

SP = (280*80/100) = 24

Profit = 24

If the gross profit at the end of the year is Rs 30 lakh, what is A’s profit?

1. 24 lakh
2. 12 lakh
3. 18 lakh
4. 6 lakh

Ans: A:3x, B = x

Ratio of profit = 3:1

Gross profit = Rs 30,00,000

share of B working part new = 12*50000 = 600000

Remaining profit = 24,00,000

A’s share = 18 lakhs

2. 4/7 or 4
3. -4/7 or 4
4. 4/7 or -4

Ans: (7k+2)^2 – 4(7k-3)(2k+1) = 0

1. 8 km
2. 12 km
3. 10 km
4. 16 km

Answer:-let speed of boat = 2x, speed of water flow = x

speed downstream = 3x, speed upstream = x
