Answer 1

Answer:-

[Logic/Reason :- Add all the digits and multiply the sum with 2]

1] 35+48=40

3+5+4+8=20

20×2=40

2] 23+34=24

2+3+3+4=12

12×2=24

3] 15+25=26

1+5+2+5=13

13×2=26

4] 11+21=?

1+1+2+1=5

5×2=10

Therefore 11+21=10.

Answer 2

Step-by-step explanation:

First split them then do addition. After addition, multiply them with 2.

35 + 48 = 40

(3 + 5 + 4 + 8) × 2 = 20*2 = 40

23 + 34 = 24

(2 + 3 + 3 + 4) × 2 = 12*2 = 24

15 + 25 = 26

(1 + 5 + 2 + 5) × 2 = 13*2 = 26

11 + 21 = 10

(1 + 1 + 2 + 1) × 2 = 5*2 = 10
