Question
A started a business with an investment of Rs.1400.
After some months, B joins the business with an investment of Rs.2400 and after two more months C joins the business with Rs.2400. If the annual profit share of A and B is equal, then find for how many months C invested his money?Solution
Let B joined after ‘x’ months. => 1400 x 12 : (12 - x) x 2400 : 1400 x (12 – x – 2) => 1400 x 12 : (12 - x) x 2400 : 1400 x (10 – x) => 1400 x 12 = (12 - x) x 2400 => 12 – x = 7 => x = 5 C invested his money = 10 – x = 5 months

- What will come in place of (?) in the given expression.
(84 + 36 ÷ 6) × 2 = ? What value should come in place of the question mark (?) in the following question?
15 × 19 – 13 × 5 = 122 ...
18(1/3) + 9(2/3) – 10(1/3) = 1(2/3) + ?
Simplify the following expressions and choose the correct option.
{(4/9 of 567) + √1936} ÷ 8 = ?
5/13 × 104 + 1(2/9) × 198 = 133 + ?
