If 9+2=711
14+6=820
17+11=628
Then what is
12+3=????
Answers
Answer:
915
Step-by-step explanation:
Given:
9 + 2 = 711
14 + 6 = 820
17 + 11 = 628
To find:
12 + 3
Solution:
We know that sum of 9 and 2 is 11. Similarly sum of 14 and 6 is 20 and sum of 17 and 11 is 28.
If we check the question then we find that it is given that sum of 9 and 2 is 711 but the sum of 9 and 2 is 11. Similarly, the sum of 14 and 6 is 820 but in actual it is 20.
In first case 7 is written first and in second case 8 is written first. Similarly, in third case 6 is written first. Each time one number is increasing and decreasing. Firstly 7 then 8 then 6.
There is one more way i.e. 9 - 2 = 7, 14 - 6 = 8, 17 - 11 = 6 which is their first number.
So, 12 - 3 = 9 and the 12 + 3 = 15
So what we have to do is firstly subtraction then addition.
Hence, the value of 12 + 3 is 915.
