Let selling price for both clocks is x taka Purchasing price of A is = x/1.2 taka Purchasing price of B is = x/0.75 taka Now (x/1.2) + (x/0.75 ) = 650 ⇒ (100x/120) + (100x/75) = 650 ⇒ x/120 + x/75 = 650/100 ⇒ x (5 + 8)/600 = 650/100 ⇒ x = (650 × 600)/ (100 × 13) = 300 Taka Purchasing price of A is = x/1.2 taka = 300/1.2 taka = 250 taka Purchasing price of B is = x/0.75 taka = 300/0.75 = 400 takaRelated questions
