Answer 1

Each card has 4 circles and 5 triangles..
So for every card there will be an extra triangle..
So 1 card = 1 extra triangle..
Accordingly danish needs to have 27 cards which corresponds to 27 more triangles than the circles overall..

Hope it helped..

Answer 2

Danish has 27 such types of printed cards.

• According to the figure given in question,

Number of circles printed on the card = 4

Number of triangles printed on the card = 5

Extra number of triangle per card = 5 – 4 = 1

• Number of cards such that Danish has 27 more triangles

                   = 27 / extra triangle per card

                   = 27 / 1

                   = 27
