Question

find q in the addition 31q+1q3



good after noon to every one ​

Answer 1

Answer:

Here, 31 Q + 1 Q 3 = 501 31Q+1Q3=501 If we add unit digits Q Q and 3 3, it becomes Q + 3 Q+3. So, Q + 3 Q+3 should be equal to the unit digit of 501 501 that is 1 1. So, Q Q can be 8 8. If we replace Q Q by 8 8 and verify the addition, it satisfies the addition. So, Read more on Sarthaks.com - https://www.sarthaks.com/1128852/find-q-in-the-addition-31q-1q3-501?show=1129172#a1129172

Answer 2

Answer:

Solution: Here, 31Q+1Q3=501

If we add unit digits Q and 3, it becomes Q+3.

So, Q+3 should be equal to the unit digit of 501 that is 1.

So, Q can be 8. If we replace Q by 8 and verify the addition, it satisfies the addition. So,

Q=8
