A number when divided by 46 gives 11 as quotient and 15 as remainder. The number is

• 491

• 521

• 701

• 679

Answer explanation

To find the number, use the formula: Number = (Quotient * Divisor) + Remainder. Substituting the values, we get: Number = (11 * 46) + 15 = 521. Therefore, the correct number is 521.

In a division sum, we have dividend = 199, quotient = 16 and remainder = 7. The divisor is

• 11

• 23

• 12

• none of these
