X spends 15% of his pocket money on food & 20% remaining of new shirt . If he is left with rs.1360 ,how much did the new shirt cost x?
Let the pocket money be= Rs x
Money spent on food= 15x/100
Money spent on shirt= 0.2*15x/100=3x/100
Money left= x-(15x/100+3x/100)= 82x/100
And this is given to be = Rs 1360
So, 82x/100=1360 which gives x = 1360*100/82
Cost of shirt is therefore= (0.03*1360*100)/82= Nearly Rs 50
