Question

Which one will replace the Q mark?

(a) 18 (b) 12

(c) 9 (d) 6

Directions: The two questions (10 and 11) are based on the following information given:

• A. A cuboid shaped wooden block has 6 cm length, 4 cm breadth and 1 cm height.
• B. Two faces measuring 4 cm x 1 cm are coloured in black.
• C. Two faces measuring 6 cm x 4 cm are coloured in green.
• D. The block is divided into 6 equal cubes of side 1 cm (from 6 cm side), 4 equal cubes of side 1 cm (from 4 cm side).

Answer 1

The correct option is C

Two faces measuring 6 cm x 4 cm are coloured in green.

(12 + 18 + 30)/10 = 6

(16 + 24 + 40)/10 = 8

Similarly, (45 + 18 + 27)/10 = 9.
