• 234
• 345

50 hens --- 100 eggs ---- 1 day
1 hen --- 2 eggs ---- 1 day

Ques12. Population of a town 3 years ago was ‘ b ‘ and population of the town 3 years from now will be ‘ c’ . What is the current population of the town?

• √(bc)
• √(dc)
• √(ac)
• √(c)

Solution: 

Let the population increases at the rate of r per year and present population is x, then
b[1+(r/100)]^3 = x

 

• [1+(r/100)]^3 = x/b

 

Also

x[1+(r/100)]^3=c

•  x*x/b= c or x^2= bc

Hence

x= √(bc)

Ques 13.4 men can repair a road in 7 hours. How many men are required to repair the road in 2 hours?

• 12
• 13
• 11
• 14

Explanation :
No. of Men x Time taken / Work = Constant
So, here we apply
M1 x T1/ W1 = M2 x T2 / W2
Given that, M1 = 4 men, T1 = 7 hours; T2 = 2 hours, we have to find M2 =?
Note that here, W1 = W2 = 1 road, ie. equal work load.
Clearly, substituting in the above equation we get,
4 * 7 = M2 * 2
M2= 14 men.

therefore, x=11
hence,
Ram's age= 16
Ram's age after 2 yrs=16+2=18 yrs

37 – 26 = 11

We can see that an A.P. is formed of odd numbers .

So the series will be  5, 10, 17, 26, 37, 50, 65, 82, 101, 122, 145…

The 11th term is 145

15 = 3× 5
20 = 2×2×5 = 2^2×5
27 = 3×3×3 = 3^3
HCF = 1
LCM = 2^2 × 3^3 × 5 = 540
