Question
Four persons ‘A’, ‘B’,
‘C’ and ‘D’ have different amounts with them. ‘D’ has twice amount than that of ‘A’. The amount ‘B’ has is 12.5% more than that of ‘D’. The amount ‘C’ has is equal to the average amount all four persons have. If the sum of the average amount all four have and the amount ‘A’ has is Rs. 880, then find the amount ‘B’ has.Solution
Let ‘A’ has Rs. a Therefore, amount possessed by ‘D’ = Rs. 2a Amount possessed by ‘B’ = 1.125 × 2a = Rs. 2.25a Let the average amount possessed by all four be Rs. x Therefore, amount possessed by ‘B’ = Rs. x According to the question, 2.25a + 2a + a = 4x – x Or, 5.25a = 3x Or, x/a = 7/4 Therefore, a = 880 × 4/11 = Rs. 320 Amount possessed by ‘B’ = 2.25a = Rs. 720
- What will come in place of (?), in the given expression.
(56 × 3) + (480 ÷ 6) = ? 40% of 220 × 15 ÷ 20 = ?
Simplify the following expressions and choose the correct option.
(3/4 of 528) − (2/3 of 135) = ?
√ (12+√ (12+√ (12+ ⋯ ∞ ))Â
34 × 2.5 + 6.4 × 1.5 – 4.8 × 1.2 =?
{(81% of 800 + 28 × 4) – 27 × ?} = 11 × 20
What should come in place of (?) question mark in the given expression.
[60% of 350 + (2/7 of 210)] ÷ 5 = ?
What will come in the place of question mark (?) in the given expression?
24% of 350 + 246 = ? + 50 × 2.5
