Question
490 sweets were distributed equally among children in
such a way that the number of sweets received by each child is 40% of the total number of children. How many sweets did each child received?Solution
Let the total number of children be x. Then, => x × (40% of x) = 490 => x2 = (490 × 100)/40 => x2 = 1225 => x = 35 Number of sweets received by each child = 40% of 35 = 14
Evaluate:
β729 + β49 - β16 + 1/β64
Simplify:

(1/5)(40% of 800 β 120) = ? Γ 5
2/5 of 3/4 of 7/9 of 7200 = ?
`sqrt(5476)` + 40% of 1640 = ? `xx` 4 - 2020
? = (22% of 25% of 60% of 3000) + 21
Determine the simplified value of the given mathematical expression.
(342 β 20% of 5280) = ? Γ· 3
β157464 =?
