Solution

✅ Correct Option: 2

A number when divided by 95 leaves a remainder 43. The same number divided by 19 needs to be found.

If a number gives remainder 43 when divided by 95, it can be written as:

N=95k+43N = 95k + 43

where kk is the quotient.


Breaking down 95 and 43 using 19:

95=19×595 = 19 \times 5

43=19×2+543 = 19 \times 2 + 5


Substituting into the equation:

N=95k+43N = 95k + 43

N=(19×5)k+(19×2+5)N = (19 \times 5)k + (19 \times 2 + 5)

N=19×5k+19×2+5N = 19 \times 5k + 19 \times 2 + 5

N=19(5k+2)+5N = 19(5k + 2) + 5


The final form shows:

N=19(5k+2)+5N = 19(5k + 2) + 5

This means the number equals 19 times some integer, plus 5.

Therefore, when NN is divided by 19, the remainder is 55.
