Question
Aman, Bhanu, and Chetna joined a business, investing Rs.
1200, Rs. 1600, and Rs. 'r', respectively. After 6 months, Aman, Bhanu, and Chetna increased their investments by Rs. 'r', Rs. 'r', and Rs. 800, respectively. At the end of 15 months, Aman's share of the total profit of Rs. 5200 is Rs. 1800. Determine the value of 'r'.Solution
ATQ, Ratio of profit share of ‘Aman’, ‘Bhanu’ and ‘Chetna’, respectively = [1200 × 15 + r × 9]:[1600 × 15 + r × 9]:[r × 15 + 800 × 9] = [6000 + 3r]: [8000 + 3r]:[5r + 2400] So, (3r + 6000)/(11r + 16400) = 1800/5200 = 9/26 Or, 78r + 156000 = 99r + 147600 Or, 21r = 8400 Or, r = 400
What will come in the place of question mark (?) in the given expression?
√(? - 212) - 84 = 81 - 13 X 9
Evaluate: 18 ÷ 3 × 4 + 6 − 5
7(1/2) – 3(5/6) = ? − 2(7/12)
`2(1/3)` + `4(1/4)` + `4(2/3)` + `8(7/6)` + ? = `4(3/5)xx4(1/2)`
...89 ÷ 512 × (1/64) = (23)?
What should come in place of the question mark (?) in the following question?
2 – [6 – {3 + (–4 + 5 + 1) × 8} + 12] = ?
The value of 15 × 14 – 30 + (32 + 17) is:
1440 ÷ 12 + 540 ÷ √36 + ? = 180 * 3
[(15)³ × (8)²] ÷ (90 × 6) = ?²
What will come in place of the question mark (?) in the following question?
24.30% of 372.32 = ?
