Question

find the smallest digit that should be replaced at as asterrisk place in the following number so that the number 172 3 *4 is divisible by 11​

Answer 1

Answer:

We know that the divisibility rule for 11,

Consider the part Aof the question,

8∗9484

8+9+8−(∗+4+4)=0

∗=25−16

∗=9 (9 is less than 11)

Hence, the value of ∗=9

Consider the part B 

9∗53762

9+5+7+2−(∗+3+6)=0

∗=14 

since 14 is greater than 11,

On performing 1114 , we get quotient=1 , reminder=3

∗=3

Hence, the value of ∗=3
