Answer 1

Answer:

A1

Step-by-step explanation:

×5................... ..

Answer 2

Answer:

a=5, b=5, c=2

Step-by-step explanation:

1*5=5

so, ones digit of answer or alphabet b= 5

If a=1, 11*5=55 which is not satisfying

If a=2, 21*5=105 which is not satisfying

If a=3, 31*5=155 which is not satisfying

If a=4, 41*5=205 which is not satisfying

If a=5, 51*5=255 which is satisfying as b was 5 and a is same in the multiplicant as well as product. So, if two conditions are fulfilled, we can say that the values of a, b and c respectively are 5, 5 and 2.

The method I used is known as TRIAL AND ERROR METOD which can be done when options are given or when such questions are asked where values of a, b and c are between 1 and 9. Do not try this method everywhere!
