Answer 1

Answer:

A=2 and B=1.

Step-by-step explanation:

Given,

Given, 5 A

Given, 5 A+ B 3

Given, 5 A+ B 3

Given, 5 A+ B 3 6 5

Given, 5 A+ B 3 6 5

Given, 5 A+ B 3 6 5 In 1

Given, 5 A+ B 3 6 5 In 1 ′

Given, 5 A+ B 3 6 5 In 1 ′ s column,

Given, 5 A+ B 3 6 5 In 1 ′ s column,A+3=5 or a number whose unit digit is 5

Given, 5 A+ B 3 6 5 In 1 ′ s column,A+3=5 or a number whose unit digit is 5∵A is a single digit so the value to be taken is from 0 to 9.

Given, 5 A+ B 3 6 5 In 1 ′ s column,A+3=5 or a number whose unit digit is 5∵A is a single digit so the value to be taken is from 0 to 9.If we take the maximum value i.e., 9,

Given, 5 A+ B 3 6 5 In 1 ′ s column,A+3=5 or a number whose unit digit is 5∵A is a single digit so the value to be taken is from 0 to 9.If we take the maximum value i.e., 9,Then, A+3=9+3=12

Given, 5 A+ B 3 6 5 In 1 ′ s column,A+3=5 or a number whose unit digit is 5∵A is a single digit so the value to be taken is from 0 to 9.If we take the maximum value i.e., 9,Then, A+3=9+3=12

Given, 5 A+ B 3 6 5 In 1 ′ s column,A+3=5 or a number whose unit digit is 5∵A is a single digit so the value to be taken is from 0 to 9.If we take the maximum value i.e., 9,Then, A+3=9+3=12=5

Given, 5 A+ B 3 6 5 In 1 ′ s column,A+3=5 or a number whose unit digit is 5∵A is a single digit so the value to be taken is from 0 to 9.If we take the maximum value i.e., 9,Then, A+3=9+3=12=5Therefore, A=5−3=2, and there is no carry forward.

Given, 5 A+ B 3 6 5 In 1 ′ s column,A+3=5 or a number whose unit digit is 5∵A is a single digit so the value to be taken is from 0 to 9.If we take the maximum value i.e., 9,Then, A+3=9+3=12=5Therefore, A=5−3=2, and there is no carry forward.In 10

Given, 5 A+ B 3 6 5 In 1 ′ s column,A+3=5 or a number whose unit digit is 5∵A is a single digit so the value to be taken is from 0 to 9.If we take the maximum value i.e., 9,Then, A+3=9+3=12=5Therefore, A=5−3=2, and there is no carry forward.In 10 ′

Given, 5 A+ B 3 6 5 In 1 ′ s column,A+3=5 or a number whose unit digit is 5∵A is a single digit so the value to be taken is from 0 to 9.If we take the maximum value i.e., 9,Then, A+3=9+3=12=5Therefore, A=5−3=2, and there is no carry forward.In 10 ′ s column,

Given, 5 A+ B 3 6 5 In 1 ′ s column,A+3=5 or a number whose unit digit is 5∵A is a single digit so the value to be taken is from 0 to 9.If we take the maximum value i.e., 9,Then, A+3=9+3=12=5Therefore, A=5−3=2, and there is no carry forward.In 10 ′ s column,5+B=6

Given, 5 A+ B 3 6 5 In 1 ′ s column,A+3=5 or a number whose unit digit is 5∵A is a single digit so the value to be taken is from 0 to 9.If we take the maximum value i.e., 9,Then, A+3=9+3=12=5Therefore, A=5−3=2, and there is no carry forward.In 10 ′ s column,5+B=6⇒B=6−5=1

Given, 5 A+ B 3 6 5 In 1 ′ s column,A+3=5 or a number whose unit digit is 5∵A is a single digit so the value to be taken is from 0 to 9.If we take the maximum value i.e., 9,Then, A+3=9+3=12=5Therefore, A=5−3=2, and there is no carry forward.In 10 ′ s column,5+B=6⇒B=6−5=1Hence, A=2 and B=1.
