Find the remainder when 38 + 71+ 85 is divided by 16.

Answer»

Solution :When we divided 38,71 and 85 we obtain the respective REMAINDERS as 6,7 and 5. Now we can obtain the requried remainder by dividing the sum of remainders (i.e.,6+7+5=18) by 16, which is 2 instead of DIVING the sum of actual given NUMBERS (i.e., 38+71+85=194) by 16, which also gives US the same reminder 2.
