Question

2, 3, 4=198 1, 2, 3=198 4, 6, 5=99 Then, 3, 4, 7=?

Answer 1

Given:

2, 3, 4 = 198 1, 2, 3 = 198 4, 6, 5 = 99

We have to find the value of 3, 4, 7 = ?

Solution:

The pattern follow:

a, b, c = cba - abc

2, 3, 4 = 432 - 234 = 198

1, 2, 3 = 321 - 123 = 198

4, 6, 5 = 564 - 465 = 99

Similarly,

3, 4, 7 = 743 - 347 = 396 = ?

∴ Missing number (?) = 396

Thus, if 2, 3, 4 = 198 1, 2, 3 = 198 4, 6, 5 = 99, then "3, 4, 7 = 396".

Answer 2

Answer:

3, 4, 7 = 396

Step-by-step explanation:

The pattern followed in the given series is:

a, b, c = cba - abc

2, 3, 4 = 198

⇒ 432 - 234 = 198

1, 2, 3 = 198

⇒ 321 - 123 = 198

4, 6, 5 = 99

⇒ 564 - 465 = 99

3, 4, 7 =

∴ 743 - 347 = 396
