Question 60

P is increased successively by 15% and 20% to get Q. If P = 200, then what is the value of Q?

Solution

P is increased successively by 15% and 20% to get Q.

Q = P of (100+15)% of (100+20)%

Q = P of 115% of 120%

As per the question, here P = 200.

Q = 200 of 115% of 120%

= $$200\times\frac{115}{100}\times\frac{120}{100}$$

= $$2\times115\times\frac{6}{5}$$

= $$23\times12$$

= 276

Value of Q = 276
