Question
P gave out 'a' cookies to Q, R, S, and T. The cookies
received by Q and S are in a 4:7 ratio, and those received by R and T are in a 2:3 ratio. If R received 50% more cookies than Q and S received 18 fewer cookies than T, what is the value of 'a'?Solution
ATQ, Let the number of cookies received by Q and S are 4p and 7p respectively. So the number of cookies received by R = 4p Γ 1.50 = 6p Number of cookies received by T = 6p Γ 3/2 = 9p According to question: 9p β 7p = 18 2p = 18 p = 9 So the value of βaβ = 9 Γ (4 + 7 + 6 + 9) = 9 Γ 26 = 234
√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 = ?
