Question
Amit and Vinod commenced a business with initial
investments of Rs. 10,000 and Rs. 15,000, respectively. After four months, Amit doubled his investment, and Vinod withdrew Rs. 5,000 from his initial investment. At the end of the year, the company's total profit was Rs. 51,000. What is Vinod's share of the profit?Solution
ATQ, Ratio of profit shares of 'Amit' and 'Vinod' = {(10000 Γ 4) + (10000 Γ 2 Γ 8)}:{(15000 Γ 4) + (15000 - 5000) Γ 8} = {(40000 + 160000):(60000 + 80000)} = 2,00,000:140000 = 10:7 So, profit share of 'B' = 51000 Γ (7/17) = Rs. 21,000
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 =?
