IBM Company Numerical Ability Ratio and Proportion

A COMPANY BOUGHT TWICE AS MANY SMALL ENVOLOPES AS LARGE ENVOLOPES .IT USED UPTO 1/13 OF THE SMALL ENVOLOPES AND 5/6 OF THE LARGE ENVOLOPES.WHAT FRACTION OF THE TOTAL NUMBER WAS LEFT UNUSED?

Read Solution (Total 1)

Let small envelopes bought=2x
Large envelopes bought=x
Total No. of envelopes bought=x+2x=3x
Small envelope unused=(12/13)*2x=24x/13
Large envelope unused=(1/6)=x/6
Total envelope unused=(24x/13)+(x/6)=157x/78
Fraction of the total envelope unused=(157x/78)/3x=157/234
