If 16 ÷ 4 = 74; 21 ÷ 7 = 33; 81 ÷ 9 = 99 Then 55 ÷ 5 = ??

Question

if 3+4=21 , 5+6=55 , 2+7=18 then how much is 6+8=?

Answer 1

ANS:1011
(5+5)=10 & 55/5=11

Answer 2

55/5 = 11 & (5+5)=10
Answer = 1011

Answer 3

The numbers in the equations are of the form.
ab ÷ c = (a+b),(ab ÷ c)

So in case of the first equation we have;

16 ÷ 4 = (1 + 6),(16 ÷ 4) = 74

Similarly we can try with the other 2 equations;

21 ÷ 7 = (2 + 1),(21 ÷7) = 33

&

81 ÷ 9 = (8 + 1),(81 ÷ 9) = 99

Hence we can find the missing number as;

55 ÷ 5 = (5 + 5),(55 ÷5) = 1011

Answer: 1011
