Question
The cost price of a rice bag is
40% of the cost price of a sugar bag. The rice bag is sold at a 60% profit, while the sugar bag is sold at a 25% loss. If the difference between their selling prices is Rs. 16.50, what is the cost price of the rice bag?Solution
ATQ, Let cost price of a Sugar bag be Rs. 100b Cost price of a Rice bag = Rs. 40b Selling price of Rice bag = 1.6 Γ 40b = Rs. 64b Selling price of Sugar bag =0.75 Γ100b = Rs. 75b According to question, 75b β 64b = 16.5 11b = 16.5 b = 1.5 Cost price of a Rice bag = 40 Γ1.5 = Rs. 60
Evaluate:
β729 + β49 - β16 + 1/β64
Simplify:

(1/5)(40% of 800 β 120) = ? Γ 5
2/5 of 3/4 of 7/9 of 7200 = ?
`sqrt(5476)` + 40% of 1640 = ? `xx` 4 - 2020
? = (22% of 25% of 60% of 3000) + 21
Determine the simplified value of the given mathematical expression.
(342 β 20% of 5280) = ? Γ· 3
β157464 =?
