need the explanation !!

Answer 1

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
