More descriptive way :-
The computer centre spends 3/4 of 1440 (ie,1080/-)for heavy duty tapes.
That means they are spending 360/- (ie,1440-1080) for regular tapes.
With 1080 Rs they can buy 36 units (ie,1080/30)
With 360 Rs they can buy 15 units (ie,360/24)
Again with the new prices :
To buy 36 units : 36*28= 1008
To buy 15 units : 15*23= 345
Total=1353
How much will they save a month under the new prices?
Ans= 1440-1353 = 87
