Given:
Number of the last idli that the man ate = 100
Number of more idlis that the man ate each day = 6
To find:
How many idlis did the man eat yesterday.
Solution:
Let the number of idlis that the man eats be x on the first day. Then the number of idlis in the consecutive days will be:
2nd day = x + 6
3rd day = x+ 12
4th day = x + 18
5th day = x + 24
And the equation according to the given question will be:
x + x+6 + x+ 12 + x + 18 + x + 24 = 100
5x + 60 = 100
5x + 40
x = 8
Thus the number of idlis that the man eats yesterday i.e. on the 4th day will be:
= x + 18
= 8 + 18
= 26
Option A is correct.
