Question
A started a business with an investment of Rs.1200.
After some months, B joins the business with an investment of Rs.3600 and after two more months C joins the business with Rs.2800. 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. => 1200 x 12 : (12 - x) x 3600 : 2800 x (12 – x – 2) => 1200 x 12 : (12 - x) x 3600 : 2800 x (10 – x) => 1200 x 12 = (12 - x) x 3600 => 12 – x = 4 => x = 8 C invested his money = 10 – x = 2 months
?% of (168 ÷ 8 × 20) = 126
20% of 1500 – 75% of 200 = 125% of ?
Find the value of 16 X [(8 - 5) of 12 ÷ 4].
√196 + (0.25 × 144) + 19 = ? + 72
22 * 6 + 45% of 90 + 65% of 180 = ?
52% of 400 + √(?) = 60% of 600 - 25% of 400
(25 × 12 + 30 × 8 – 22 × 10) = ?
What will come in the place of question mark (?) in the given expression?
(240% of 175 ÷ √16) X 6 + 80% of 400 = ?3 + 179 + 42
What will come in the place of question mark (?) in the given expression?
(144 × 16 ÷ 12) × 6 = ?
808 ÷ (128)1/7 + 482 = 4 × ? + 846
