Question
The combined average cost price of two items, Almonds
and Walnuts, is Rs. 450. If Almonds are sold at a profit of 50% and Walnuts at a loss of 25%, resulting in an overall profit of 10%, determine the cost price of Almonds.Solution
ATQ, The sum of cost price of items 'Almonds' and 'Walnuts' = 450 × 2 = Rs. 900 Let the cost price of item 'Almonds' = Rs.'a' Then, cost price of item 'Walnuts' = Rs.(900 - a) Selling price of item 'Almonds' = a × 1.5 = Rs.'1.5a' Selling price of item 'Walnuts' = (900 - a) × 0.75 = Rs.(675 - 0.75a) Overall profit earned = {1.5a + (675 - 0.75a)} - 900 = 900 × 0.1 Or, 675 + 0.75a - 900 = 90 Or, 0.75a = 990 - 675 So, a = 315 ÷ 0.75 = 420
2(3/4) of 2880 + 54% of 7520 - ? = 302
√(?) ² = √7396 - √6889
13.5% of (100 + ?) = 27
(180 ÷ 22 ) ÷ (60% of 30) = (? ÷ 2)
5/2 of 5/6 of 12/5 of 54 % of 5250 = ?
√9604 + ∛205379 + 58% of 1500 = 520 + ?
`(sqrt(1296)xx42)/(120+200)` = ?
(43/10) + (4.2/1.2) - (2.7/3) = (?/4) + (2.7/6.0)
√ [? x 11 + (√ 1296)] = 16
520% of 360 – 12% of 400 = ? x 4
