Question
"Pawan" and "Qureshi" start a
business by investing Rs. 'p' and Rs. 'q', respectively. After the first 6 months, "Pawan" raises his investment by 25%, while "Qureshi" lowers his investment by 33.33%. After another 6 months, "Pawan" reduces his investment by 40%, and "Qureshi" boosts his investment by 50%. By the end of 24 months, their profit-sharing ratio stands at 9:11. Determine the ratio of "Qureshi's" initial investment to "Pawan's".Solution
ATQ, Ratio of profit shares of 'Pawan' and 'Qureshi', respectively: = {(p × 6 + (5p/4) × 6 + (3p/4) × 12) :(q × 6 + (2q/3) × 6 + (q × 12) } = {(6p + 15p/2 + 9p) :(6q + 4q + 12q) } = (45p:44q) ATQ, (45p/44q) = (9/11) Or, (p/q) = (9/11) × (44/45) So, (p/q) = (4/5) Let 'p' = 4x and 'q' = 5x. Therefore, required ratio = (q/p) = (5x/4x) = 5:4
- What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)
{(√2305) % of 74.69} × 15.21 - 27.89 × 44.88 + 45.12% of 2399.87
(21.02% of 600.15 ) × 14.95 = ? 2 + 29.99 × 3456 ÷ 1152
28.11 × 3.98 + 29.03 × 3.12 – 34.95 + 95.9 × 4.02 =?
(?)2 + 8.113 = 28.92 – 73.03
70.008% of 399.98 + ?% of 399.999 = 80.105% of 599.998
657.94 + 335.21 - 211.09 - 82.30 = ?
