Rakesh had rupees 80. He brought food items for half the amount. He bought books worth rupees x and he has left with money that is 3 times the x. Find the cost of book and left money him with... please send the correct answer​

Answer 1

Step-by-step explanation:

Half the amount is ₹80/2=₹40.

Then,after that linear equation becomes,

40-x=3x

40=3x+x

40=4x

40/4=x

x=10

Therefore cost of book is ₹10 and money left with him is (40-x) which is ₹40-₹10=₹30.
