Price = p
initially price reduced by 25% which means new price is 3/4P
Now on this new price further 20percent is reduced which means the new price is merely 80percent of 3/4P
==> (3/4)x(4/5)P = 12/20P is the new price after both deduction which is 60percent of the original value P. This implies this entire series of deduction is worth having discounted 40% of P. So answer is B = 40%

Let price be Rs 100
then 1st reduction will give discounted price as Rs 75
again 2nd reduction will yield 75(1-20/100)
=Rs 60 (final price)
so reduction from initial Rs 100 to final Rs 60 =40
Ans B.

\(-25 - 20 + \frac{(-25)(-20)}{100}\)

= \(-45 + 5\)

= \(-40\), Answer must be (B)
