Question

64% of 175 - 13 of [23 - {54+(3-9)+8}+12] = ?​

Answer 1

Answer:

Missing number (?) = 96

We have,

2(3)4 = 14

, 3(4)6 = 60  and 4(5)7 = ?

To find, the value of missing number (?) =

The pattern follow:

[(First number × Second number) + (Third number × First number)] ×

(Third number - First number)

14 = [(2 × 3) + (4 × 2)] × (4 - 3) =  [6 + 8] × 1 = 14

60 = [(3 × 4) + (6 × 3)] × (6 - 4) =  [12 + 18] × 2 = 60

Similarly,

? = [(5 × 4) + (7 × 4)] × (7 - 5) = [20 + 28] × 2 = 48 × 2 = 96

∴ Missing number (?) = 96
