Question
P started a business investing Rs.15000. After 4 months,
Q joined her with the capital of Rs.20000. After another 6 months, R joined them with the capital of Rs.30000. At the end of the year, they made a total profit of Rs.6000. Find the share of R.Solution
P invested her capital for 12 months, Q for 8 months and R for 2 months. So, ratio of their capitals = (15000 × 12):(20000 × 8):(30000 × 2) ⇒  180000 : 160000 : 60000 ⇒  9 : 8 : 3 Therefore, R’s share = 6000 x (3/20) = Rs.900
What approximate value should replace the question mark?
12.45% of 640.20 − 60% of 2500 = ? − 9000.10
`[(7.99)^2 - (13.001)^2 + (4.01)^3]^2=` ?
- What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)
What value should come in place of question mark (?) in the following question. (You need not to calcualte the exact value)
?/647 = 226/ ?
- What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)
A, B & C have Rs.1550 together. If they divide the money in the ratio 1:3:1 respectively. Find the difference of amount received by B and C.
What approximate value should come in the place of (?) in the following questions?
∛(92.8 + √1025) * ? = 16.06% of 750
√1024.21 × √624.89 ÷ 4.98 + 11.99 × 4.01 = ?
√784 × 3 + (713.99 ÷ 6.98) = ?% of 619.99
11.11% of (123.45 + 234.56) + 10.01³ - (5.05 of 7.07) = ? of (88.88 - 33.33)
