Therefore, number of 50 p coins, 25 p coins and 20 p coins are 400, 600, 800 respectively. If 2A = 3B = 4C, find A : B : C Solution: Let 2A = 3B = 4C = x So, A = x/2 B = x/3 C = x/4 The L. M of 2, 3 and 4 is 12 Therefore, A : B : C = x/2 × 12 : x/3 × 12 : x/4 = 12 = 6x : 4x : 3x = 6 : 4 : 3 Therefore, A : B : C = 6 : 4 : 3 6.

If x : y = 1 : 2, find the value of (2x 3y) : (x 4y) Solution: x : y = 1 : 2 means x/y = 1/2 Now, (2x 3y) : (x 4y) = (2x 3y)/(x 4y) [Divide numerator and denominator by y.] = [(2x 3y)/y]/[(x 4y)/2] = [2(x/y) 3]/[(x/y) 4], put x/y = 1/2 We get = [2 (1/2) 3)/(1/2 4) = (1 3)/[(1 8)/2] = 4/(9/2) = 4/1 × 2/9 = 8/9 Therefore the value of (2x 3y) : (x 4y) = 8 : 9 More solved problems on ratio and proportion are explained here with full description.4.
