Answer 1

Answer:

3

Step-by-step explanation:

Hens on 1 st Day  = 1  + 7 (birth)

Hens on 2nd Day = Hens on 1st Day + (hens birth on 1st Day) * 7

= 1 + 7  + 7²

Similarly on 3rd day = 1 + 7 + 7² + 7³

on 365 day = 1 + 7 + 7² + 7³  + .......................................+ 7³⁶⁵

Total 366 terms

on dividing by 5

ist term gives remainder  1  

2nd term  gives remainder  2

3rd term  gives remainder  4

4th term  gives remainder  3

then this sequence repeats

Total 366 terms = 91 * 4 + 2

sum of remainders = 91 * ( 1 + 2 + 3 + 4) 1 + 2

= 91 * 10 + 3

91 * 10  is divisible by 5

hence remainder = 3

The no of hens which the krishna had received is = 3
