Question

I have 150. With 0.3 part of my money I bought exercise books and with 0.4 part I bought
story book. Let me find, what amount of money is left with me.​

Answer 1

Total money =150

money spend in books = 0.3

0.3*150= 3/10*150= 45

money spend in story book = 0.4

0.4*150= 60

Total money spend= 45+60= 105

money left = Total money- spend money

150-105= 45

Money left is 45
