Question

Which of the following numbers should be added to 11158 to make it exactly divisible by 77?
1. 9
2. 8
3. 7
4. 5

Answer 1

Answer:

7 should be added to 11158 to make it exactly divisible by 77

Step-by-step explanation:

Dividend = 11158

Divisor = 77

$Dividend = (Divisor \times Quotient)+Remainder$

$11158 = (77 \times 1)+345$

$11158 = (77 \times 14)+378$

$11158 = (77 \times 144)+70$

Reaminder = 70

Number should be added to 11158 = Divisor - remainder

                                                         =77 - 70

                                                         =7

So, Option 3 is true

Hence 7 should be added to 11158 to make it exactly divisible by 77
