Answer» Answer: 300 Rs Step-by-step explanation: we will USE them method of assumption here. First CHECK the data to ease up the calculation.1/3 and 1/4 is given , LCM of 3 & 4 is 12. So LET us assume that the Total Money he has is 12units spend 1/3 on book =1/3*12=4 units this means he spent 4 UNIT on book. Now he is LEFT with 8 units ATQ he spends 3/4 of the remainder on a pen (this statement has the main logic) it 8*3/4=6units on pen this means out of 12 units, he spend 6 units on pend & 4 units on book. NOW ATQ the difference b/w spending of book and pen is 60RS but according to our assumption it is 6units-4units=2units ATQ 2units is equal to 60rs according to statement 2units=60 1 unit=30 Total money He Spent= 10 units 10 units= 300Rs |
