Case 1)
lets assume all the days were of the same month, in that case
x + (x+1) + (x+2) + (x+3) + (x+4) = 63
5x = 53
x is coming out to be in decimal, which can not be
lets assume all the days were of the same month, in that case
x + (x+1) + (x+2) + (x+3) + (x+4) = 63
5x = 53
x is coming out to be in decimal, which can not be
Case 2)
now the other possibility is such that month changes after some days
thus there can be few possibilities
A) x + (x+1) + (x+2) + (x+3) + 1 = 63
4x = 56 => x = 14, but 1st cant come after 17th, so it is ruled out
B) x + (x+1) + (x+2) + 1 + 2 = 63
3x = 57 => x = 19, but again 1st cant come after 21, so it is ruled out as well
C) x + (x+1) + 1 + 2 + 3 = 63
2x = 56 => x = 28, this is possible for the month with 29 days, i.e. February of leap year
so thee dates were 28,29,1,2,3

Lets say G, F and S are ages of grand father, father and son in years
than
G+F+S = 140
S*12 = G
S*365 = (F*365)/7 => F = 7S
Than 12S + 7S + s = 140 => 20S = 140 => S = 7 Years
F = 49 Years
G = 84 Years
than
G+F+S = 140
S*12 = G
S*365 = (F*365)/7 => F = 7S
Than 12S + 7S + s = 140 => 20S = 140 => S = 7 Years
F = 49 Years
G = 84 Years

Money before Church 1: 187.5/2 = $93.75
Money before church 3: 150/2 = $75
Money before church 2: 175/2 = $87.5
Money before Church 1: 187.5/2 = $93.75
1st digit denotes how many zeroes
Puzzle Time challenge?
Chalo solve karo…
Its a 5 digit number where…
1st digit denotes how many zeroes are there in the number
2nd digit denotes how many ones are there in the number
3rd digit denotes how many twos are there in the number
4th digit denotes how many threes are there in the number
5th digit denotes how many fours are there in the number
Can you guess the number?
Check your answer:-
Lets say there are 4 0’s, so number should be 40000, but this violates that 5th digit tells how many 4’s are there.
Now lets say there 3 0’s then number can be 30010, but thus also violates, 2nd digit tells number of 1’s
Now if there are 2 0’s then 21200 satisfies all the conditions.
3 accessories with 100 rupees
A man buy 3 accessories with 100 rupees. first one 5 rupees, second one 3 rupees, third one 0.5 rupees each. he bought total 100 pieces. How many pieces he bought for each accessory ?
First Accessory
Second Accessory
Third Accessory
Click here to See Solution
lets say he bought x,y and z pieces.
Then we can make these two equations
Eq1: x + y + z = 100
Eq2: 5x + 3y + 0.5z = 100
Then we can make these two equations
Eq1: x + y + z = 100
Eq2: 5x + 3y + 0.5z = 100
2*Eq2 => 10x + 6y + z = 200
2*Eq2-Eq1 => 9x + 5y = 100
from this equation x should be a multiple of 5, for x = 5 => y = 11
for x = 10 => y = 2
for x = 15 or more y becomes -ve
So two possible answers
x = 5, y = 11, z = 84
x = 10, y = 2, z = 88
