Answer 1

Answer:

23.5%

Step-by-step explanation:

Let’s apply the successive discounts of 10% and 15% on amount x.

After discount of 10%, x becomes:

• x – 10% of x = 0.9x

After discount of 15%, the final amount becomes:

• 0.9x * (1-0.15)

• x*0.9*0.85

• 0.765 x

Therefore, final amount after successive discount is 0.765 x.

Now, we need to find equivalent discount to successive discounts of 10% and 15%. Let’s denote equivalent discount by ”d”.

Thus,

• 0.765x= x- d % of x

• 0.765x= x- d/100 * x

• d/100 *x= 0.235 x

• d= 23.5%

Thus, equivalent discount to 10% and 15% is 23.5%.

Answer 2

Answer:

it is 23.5 %

Step-by-step explanation:

let MRP be 100 rs

then on discount of 15%

left rupees are 100 - 15 = 85

again on discount of 10% on 85 rs

left rupees are 85 - 8.5 = 76.5

which is the final price

thus equivalent discount is

100 - 76.5 = 23.5%
