the price of a cycle is reduced by 25 per cent . the new price is reduced by a further 30 per cent . the two reductions together are equal to a single reduction of
price = p initially price reduced by 25 % which means new price is 3 / 4 p now on this new price further 30 percent is reduced which means the new price is merely 70 percent of 3 / 4 p = = > ( 3 / 4 ) x ( 7 / 10 ) p = 21 / 40 p is the new price after both deduction which is 52.5 percent of the original value p . this implies this entire series of deduction is worth having discounted 47.5 % of p . so answer is b = 47.5 %
