The cost price of 18 notebooks is caual to the selli​

Answer 1

Answer:

Let the cost of the item be x

Then,

One was sold at a profit of = x +10 %

Other was sold at the profit of = x + 15 %

Difference in their profit = 7.5

Thus ,

Their Difference = 15 % - 10 % = 5 %

then,

= x + 5 % = 7.5

= x = 7.5 - 5 / 100

= x = 7.5 - 1 / 20

= x = 7.5 × 20 - 1/20

= x = 150 - 1 ÷ 20

= x = 149 ÷ 20

= x = 14.9 ÷ 2

= x = 74 .5 is the cost of each item
