Question
Raj invested Rs.45000 in a business. After 4 months,
Rohan joins him with an investment of Rs.P. If at the end of the year the profit is Rs.65000 and profit share of Raj is Rs.45000. Find the value of P.Solution
Profit ratio of Raj and Rohan = 45000 x 12 : P x 8 = 67500:P According to the question, => 67500/P = 45000/(65000 β 45000) => P = Rs.30000
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 =?
