b) 211/1560
c) 1477/1560
d) 7/120



Answer
Solution
Correct Answer Is : 1560/1477
Solution Is : 7/8 X 13/15 + 1 = 91/120 + 1 = 91 + 120/120 = 211/120 211/120 = 13/7n => 7n X 211 = 120 X 13 => n = 120 X 13/7 X 211 = 1560/1477.

A fraction is such that when 5 is added to the numerator then its value is 1, again when 6 is added to the denominator then the value is 1/2. The fraction is

a) 16/21
b) 13/18
c) 11/16
d) 18/23



Answer
Solution
Correct Answer Is : 11/16
Solution Is : Let the fraction be X/y, X+5/y = 1 => X + 5 = y ______.(i) again, X/y+6 = 1/2 2X = y + 6 => 2X = X + 5 + 6 (from equation (i)) => 2X - X =11 => X =11 from equation (i) y = 11 + 5 = 16 X/y = 11/16
