Mr. John used to purchase certain number of mangoes for $360 Since the price of mangoes is reduced by 10% he got 12 more mangoes today. Find the original price of 120 mangoes.   Method 1:   Let price per mango = x. Let number of mangoes be n. Then, nx = 360.   Now price = 0.9x; number of mangoes = n + 12. Total amount = 0.9x*(n+12) = 360.   nx = 0.9nx + 10.8x =&gt; 0.1nx = 10.8x =&gt; n = 108 =&gt; x = 360/108 = 3.33   Original price of 135 mangoes = 135*3.33 = 450.   Answer 450
