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
