Question

5#7=20 8#9=19 6#5=16 2#4=?​

Answer 1

•Given :-

5#7=20 8#9=19 6#5=16

•To find:-

2#4=?

• Solution:-

According to the series

the format is

[ first number×(difference between two numbers) +10 + 0]

then

[first number×(difference between two numbers) +10 + 1 ]

so

5#7=20 = 5×(7-5)+10+0 = 20

8#9=19 = 8×(9-8)+10+1= 19

6#5=16 = 6×(6-5)+10+0 = 16

thus

2#4=2×(4-2)+10+1 = 15
