from 1856, so that the remainder when divided by
7, 12 and 16 will leave the same remainder 4.
(a) 137
(b) 1361
(c) 140
(d) 172​

Answer 1

Answer:

(d) 172 will leave the same remainder 4

Answer 2

Step-by-step explanation:

1856-172=1684

1684÷7=quotient =240

remainder =4

1684÷12= quotient =140 remainder =4

1684÷16=quotient =105

remainder =4

so the least number that should be subtracted is 172
