Question
Rs. 18,000 is divided among 'X', 'Y', and 'Z' such that
one-fourth of X’s share is equal to 20% of Y’s share which is equal to one-sixth of Z’s share. Find Z's share.Solution
ATQ, Let shares of ‘X’, ‘Y’ and ‘Z’ be Rs. ‘x’, Rs. ‘y’ and Rs. ‘z’, respectively. So, (x/4) = (y/5) = (z/6) So, ratio of share of ‘X’, ‘Y’ and ‘Z’ = 4:5:6 Sum of the parts = 4+5+6 = 15 So, share of ‘Chintu’ = (6/15) × 18000 = Rs.7200
(24% of 500 - 20) ÷ 25 = ? ÷ 4
If a³ - b³ = (a - b)(a² + ab + b²), find a³ - b³ when a = 10 and b = 4.
(22.5 × 24) ÷ 40 + 51.50 = ? ÷ 5.25
12.5% of 384 - 16.66% of 66 = √16 + √? + 22
44% of 1900 + 25% of ? = 9000
52% of 36% of 810 = 72% of 18% of ?Â
25% of 250 + 32% of 200 = ? ÷ √ 16
1240 ÷ ? = 242 + 123 – 514 × 4
14 × 6 + 9 × 11 = (82 – 3) × ?
What will come in the place of question mark (?) in the given expression?
