Question

1=15 2=30 4=60 6=90 8=120 11=150 12=165 15=

Answer 1

hello Priyansh
Let's find the pattern in it

1 = 1×15 = 15

2 = 2×15 = 30

4 = 4×15 = 60 ..... this the pattern of every question. till 8 = 8×15 = 120

But after 11 there is change in pattern

11 = 11×15 - 15 = 150

12 = 12×15 -15 = 165

hence

15 = 15×15 - 15 = 210

hope it helps

Answer 2

Hey!

1=15
2=30 [15×2]
4=50 [15×4]
6=90 [15×6]
8=120 [15×8
11=150 [(15×11)-15]
12=165[(15×12)-15]

Thus,

15=___[(15×15)-15]
15=210

Hope it helps...!!!
