Question

A no. When divided by 30 gives 42 as quotient and 22 as remainder.what is the no.

Answer 1

Let the no. be a
Using Euclid's division algoritm
a = bq + r
a = 30*42+22(b=divsor, q= quotient, r = remainder)
a = 1282
therefore the no is 1282

Answer 2

here divisor = 30
quotient = 42 and
remainder = 22
so,
dividend = ( divisor × quotient ) + remainder
= (30×42)+22
= 1260+22
= 1282
