Solution: let the divisor be X.

∴3x+ 10= 143- 10-x

Solution, x=30.75

∴3x+ 10= 102.25

The arithmetic method is as follows:

Because the quotient is 3 and the remainder is 10, the dividend is more than three times the divisor times 10.

143-10 = 133, and the sum of dividend and divisor is133.

Because because (dividend-10) is three times the divisor.

Divider = (133-10)/4 = 30.75.

Dividend = 30.75 * 3+10 =102.25

After all, I am not a teacher. I'm not sure. .
