Question
Person P allocated 35% of his
salary to his son for school fees. From the remaining amount, he saved 40% in his bank account. The total of the amount he saved in the bank and the amount he gave to his son was Rs 87,840. What was Person P's total salary?Solution
ATQ, Let the salary of P be 'a' Amount given to his son = a×35/100 = 7a/20 Remaining amount = a - 7a/20 = 13a/20 Amount kept in bank = (13a/20)×40/100= 13a/50 So, 13a/50 + 7a/20 = 87840 or, 26a+35a/100 = 87840 or, 61a = 87840×100 or, a = 8784000/61 a = Rs.144000
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)
