Question
A man allocates 12%, 18%, and 20% of his salary to his
three children, P, Q, and R, respectively. The children spend 50%, 60%, and 56% of their received amounts. The difference between the total money left with the children and the man is Rs. 3360. What is the man's salary?Solution
Let the salary of man = 100x He gives 12x, 18x and 20x to children Savings of man = 100x β (12x+18x+20x) = 50x Savings of P = 50% of 12x = 6x Savings of Q = 40% of 18x = 7.2x Savings of R = 44% of 20x = 8.8x Total savings of P, Q and R = 6x+7.2x+8.8x = 22x Difference = 3360 50x-22x = 3360 28x = 3360 X = 120 Total salary of man = 100x = 12,000
√3598 × √(230 ) ÷ √102= ?
15% of 2400 + (β 484 β β 256) = ?
(13)2Β - 3127 Γ· 59 = ? x 4
6269 + 0.25 × 444 + 0.8 × 200 = ? × 15
...(53 + 480 Γ· 4)% of 20 = ?% of 70
Find the simplified value of the following expression:
62 + 122 Γ 5 - {272 + 162 - 422}
(15 Γ 225) Γ· (45 Γ 5) + 480 = ? + 25% of 1240
β [? x 11 + (β 1296)] = 16
11 Γ 25 + 12 Γ 15 + 14 Γ 20 + 15 = ?
