## Karnataka Board Class 8 Maths Chapter 1 Playing with Numbers Ex 1.2

Question 1.

In the following find the digits represented by the letters.

Answer:

Here : 3 + 4 = 7 ∴ B = 4

Answer:

Here 6 + A = 1 ∴ A = 5

6 + 5 = 11 is written in units place and 1 is carried.

∴ 1 + 1 + 2 = B

∴ B = 4

Answer:

Here A × A is A.

Hence A = 0, 1, 5, or 6 If A = 1 we get 21 × 1 = 21 but the product is 12A.

If A = 5 then 25 × 5 = 125.

∴ A = 5

Answer:

Here A + A = A

Hence A = 0

Answer: Here A × A = A

Hence A = 0, 1, 5 or 6

If A = 1, then 11 × 11 = 121

∴ A = 1 and B = 2

Answer:

3A × A

36 × 6

216

∴ A = 6 & B = 1
