A number, when divided by a divisor, leaves a remainder of 24. When twice the original number is divided by the same divisor, the remainder:

(a) Is 24.

(b) Is 0.

(c) Is 12.

(d) Cannot be determined.

The divisor is 37 and as such cannot be determined from the options

How to find the divisor?

Let ‘x’ be the number which is a number when divided by a divisor leaves a remainder of 24. When twice the original number is divided by the same divisor the remainder is 11.

So let us assume d as the divisor. So divisor is a number by which another number is to be divided. Or a number that divides into another without a remainder.

So now we have ‘d’ as the divisor and ‘x’ as the number. By taking this, we will form an equation.

So we have our standard equation that is dividend = divisor × quotient + remainder

Hence now first we will write the equation for the given numbers.

So dividend(x)=divisor(d) x quotient (m) +remainder (24)

So this also can be written as:

x = md + 24 ------(i)

Then we have another statement given that When twice the original number is divided by the same divisor the remainder is 11.

So we have 2x=nd+11 ----(ii)

Hence we have twice the equation (i) as equation(ii). Thus:

2(md + 24) = nd + 11

2md + 48 = nd + 11

2md - nd = -37

d(n - 2m) = 37

d = 37/(n - 2m)

Thus, the divisor is 37.
