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

A group of friends goes for dinner and gets bill of Rs 2400. Two of them says that they have forgotten their purse so remaining make an extra contribution of Rs 100 to pay up the bill. Tell the no. of person in that group ?

Let ‘x’ be the number of perons in the group and let ‘y’ be amount per head which they have to pay.
Then xy = 2400.
or y = 2400/x
Since two friends have forget the purse, x-2 persons should share the total amount(2400).

If they share, they have to make an extra contribution of Rs 100 to pay up the bill That is x-2 persons should pay y+100 each
or (x-2)(y+100) = 2400
or y+100 = 2400/(x-2)
or y = 2400/(x-2) – 100

Therefore we have got two equations namely,
y= 2400/x and
y = 2400/(x-2) – 100

Comparing these two, we get
2400/x = 2400/(x-2) – 100

Solving this we get
x^2 – 2x -48 = 0
or (x-8) (x+6) = 0
or x = 8 or x = -6

Since ‘x’ denote the number of persons, it should be positive.
So, x = 8.

A long thin strip of width 7cm is kept on a flat surface. Another identical strip is kept on it in an overlapping manner such that the combined width of the two is 11 cm. What is the width of 55 such strips kept like this ?

11cm is combined width for 2 strips ,

11-7= 4cm is extra width for each overlapped strip.
Hence 4*53 = 212 (Remaining 53 strips)
212 + 11 = 223 (Previous 2 strips)
