Fractions and Decimals If 1.5 x a = 0.04 x b then the value of (b - a) / ( b + a) is ? None of these 730/77 73/770 73/77 None of these 730/77 73/770 73/77 ANSWER EXPLANATION DOWNLOAD EXAMIANS APP a / b = 0.04 / 1.5 = 4 / 150 = 2 / 75∴ Given Exp. (b - a) / ( b + a)= (1- a/b ) / (1 + a/b) = (1- 2 / 75) / (1 + 2 / 75)= ( 73/75 ) / ( 77/75)= 73/77

Fractions and Decimals There are two fractions such that fraction X is thrice the fraction Y and their product is 25/12. Which of the following is equal to Y? 7/8 9/10 5/6 3/4 7/8 9/10 5/6 3/4 ANSWER EXPLANATION DOWNLOAD EXAMIANS APP Let X and Y are given fractions.Given that, fraction X is thrice the fraction Y;i.e., X = 3Y ...(1)And their product = X x Y = 25/12Sub. eqn (1) in above,(3Y)x(Y) = 25/123(Y²) = 25/12(Y²) = 25/36Y = 5/6Hence the required fraction is 5/6.
