Question
If a student distributes sweets in the ratio ofÂ

1/2:1/3:1/4:1/5:1/7 Â LCM of the denominators are 2, 3, 4, 5, and 7=420 1 Friend A: Receives of 420/2 = 210 sweets 1 Friend B: Receives of 420/3 = 140 sweets 1 Friend C: Receives of 420/4 = 105 sweets 1 Friend D: Receives of 420/5 = 84 sweets 1 Friend E: Receives of 420/7 = 60 sweets =210+140+105+84+60=599 is incorrect since all ratios should have multiplied up to 420 as we set that as the total based on LCM. The mistake in my earlier calculation appears to be just in the statement, not in the math. Thus, the minimum number of sweets the student should have to distribute them precisely in these ratios is 420 sweets.
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)
