Question
If the price of tea increases by 50%, what percent
should the consumption be cut down to keep the spending constant?Answer should be rounded off to the nearest integer.Solution
ATQ,
Initial price = Rs. 100m, consumption = n
Initial expenditure = 100mn
New price = 150m
New consumption = 100mn ÷ 150m = 100n ÷ 150
Decrease = n - (100n ÷ 150) = 50n ÷ 150
Required percent = (50n ÷ 150) ÷ n × 100 = 5000 ÷ 150 ≈ 33%
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)
