Question

Identify the missing numbers in the number tower given below.

• A. A=15, B=28
• B. A=28, B=15
• C. A=16, B=16
• D. A=16, B=32

Answer 1

The correct option is D A=16, B=32

Each box has a number which is sum of the numbers on its two adjacent lower boxes.
For example, 14 has 10 and 4 below it
Therefore, 14 = 10 + 4

Since A has 12 and 4 below it,
Therefore,
12+4=16

A=16
and,
Since B has A and 16 below it,
Therefore,
16+16=32

B=32
Hence, the missing numbera are 16 and 32.
