Question
Two friends, R and S, started a venture where R’s capital
was Rs. 2,000 more than S’s. R withdrew his investment after 10 months. If the ratio of their profit shares is 11:12, then find the investment of R.Solution
ATQ,
Let the investment of S be Rs. a.
Investment of R = Rs. (a + 2000)
Profit ratio = [(a + 2000) × 10] : [a × 12] = (5a + 10000) : 6a
ATQ,
(5a + 10000) : 6a = 11 : 12
⇒ 12 × (5a + 10000) = 11 × 6a
⇒ 60a + 120000 = 66a
⇒ 6a = 120000
⇒ a = 20000
Investment of R = 20000 + 2000 = Rs. 22,000
(2879.79 ÷ 24.07) × (√624.77 + √120.88) - 35% of 1199.85 = ?
15.78% of (287 + 302) + 12³ = ?% of 170 + 8 × 14 + 3²
