A man spent 10% of his money. After spending 60% of the remainder he has Rs. 72 left. How much had he in the start?

[A].	300	[B].	50
[C].	400	[D].	200
[E].	100

Answer: Option D

Explanation:

x is the amount in the start. After spending 10% the rest is 90x/100. Now treat this remaining amount as 100% for the second transaction. After spending 60% the rest is 40% of 90x/100 that is 40/100 90x/100 = 36x/100. Now this is equal to 72. 36x/100 = 72 ? x = 200
