Question
'A' and 'B' form a partnership with an initial
investment of Rs. 2400 and Rs. 8a. After 6 months, 'A' takes out Rs. 400 from his original investment, and 'B' adds to it an amount that equals to  of 'A's original investment. Upon the conclusion of a year, if the profit ratio between 'A' and 'B' is 11:9, ascertain the value of 'a'.Solution
Ratio of profit share of 'A' to that of 'B' = Ratio of profit share of 'A' to that of 'B' = (2400 + 2000) :(8a + 8a + 400) = 4400:(16a + 400) ATQ: {4400/(16a + 400) } = (11/9) Or, 400 X 9 = 16a + 400 Or, 16a = 3600 - 400 Or, a = 200
20 * 8 + 40% of 100 + 60% of 150 = ?
7292/3 = ?
Find the result of
45 ÷ 3 of 6 of [12 ÷ 4 of (10 ÷ 2 + 1)] + (8 ÷ 2.5 + 1.8)
- What will come in place of (?), in the given expression.
144 ÷ 12 + 18 × 2 = ? (2197)1/3 + (18)2 − 121 = ? − 69 × 5
Evaluate: {2 x (0.718 + 0.982) + 0.008 of 5000}
Simplify the following expressions and choose the correct option.
18² + (27 ÷ 3) × 11 − 250 = ?
If x²- 5x + 1 = 0, what is the value of x² + 1/x2?

? ÷ 62 × 12 = 264
