Two yrs back the ratio between the ages of Mahesh and Sunil was 3:2. If Sunil is younger to Mahesh by 8 yrs, what is the present age of Mahesh?

Solution:

Let the present age of Mahesh and Sunil are x and y yrs.

Now y = x - 8 .....(ii)
from (i) & (ii)
2x = 3 (x - 8) - 2
2x = 3x - 24 - 2
x = 26 yrs.

A man buys milk at a certain price per litre and after mixing it with water sells it again at the same price. How many ml of water does he mix in every litre of milk if he makes a profit of 25%?
Solution:

∴ S. P. after 25% profit = Rs 125 per litre
Now again S. P. of 1 litre milk with water = Rs 100
∵ In Rs 100 he sells = 1 litre
∴ In Rs 125 he will sell = 1 x 125 /100 = 1.25 litre
Then quantity of water = 1.25 - 1 = 0.25 litre
= 0.25 x 1000 = 250 ml
