My 1st friend gave me 1000 and 2nd gave me 500. I have lost 1000 rupees then i purchased something with the cost of 300 and gave 100,100 both friends. 1st friend remaining 900 and 2nd remaining 400 900+400+300=1600 why ?

You had given Rs.100 to my both friends. so now you have to give only 900+400.
So total = 900 + 400 + 100 + 100 = 1500

Chocolate cost is Rs.1 and if we return 3 wrappers (covers) of chocolate we get 1 more chocolate. If you have Rs.15 how many chocolates do you get ?

I have Rs.15 = 15 Chocolates + 15 wrappers(covers)
Give 15 wrappers = we will get 5 chocolates + 5 wrappers
Give only 3 wrappers = we will get 1 chocolate + 1 wrapper
Give remaining 2 wrappers along with new 1 wrapper = we will get 1 more chocolate
so total = 15 + 5 + 1 + 1= 22

A group of friends went on a holiday to a hill station. It rained for 13 days. But when it rained in the morning, the afternoon was lovely. And when it rained in the afternoon, the day was preceded by clear morning. Altogether there were 11 very nice mornings and 12 very nice afternoons. How many days did their holiday last ?

The holiday last for 18 days.

Let’s assume the number of days as follows:

  • Rain in the morning and lovely afternoon = X days
  • Clear morning and rain in the afternoon = Y days
  • No rain in the morning and in the afternoon = Z days
  • Number of days with rain = X + Y = 13 days
  • Number of days with clear mornings = Y + Z = 11 days
  • Number of days with clear afternoons = X + Z = 12 days

Solving above 3 equations, we get X = 7, Y = 6 and Z = 5

Hence, total number of days on holiday = 18 days
