Question
Ravi had 360 candies, while Shyam
had 45 more candies than Ravi. Ravi ate 25% of his candies, and Shyam ate 35% of his candies. Now, how many more/less candies does Ravi have compared to Shyam?Solution
ATQ, Original number of candies with Shyam = 360 + 45 = 405 Number of candies left with Ravi = 360 - (360 Γ 0.25) = 270 Number of candies left with Shyam = 405 Γ 0.65 = 263.25 So, required difference = 270 - 263.25 = 6.75
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 =?
