Ans —-series is 7,16,9,15,11,14,13,13

B

128

The 3-digit number can be written as the sequence [n, 2n, 3n]
n = 1 → [1, 2, 3] → valid
n = 2 → [2, 4, 6] → valid
n = 3 → [3, 6, 9] → valid

n = 4 → [4, 8, 12] is not valid because this would lead to a 4-digit number
any value of n > 4 would also produce invalid answer

Answer: Three numbers: {123, 246, 369}

b

Answer 33
Adding 7,9.13,15,17
Correct is 35

d

24kmph

time taken = x/40 + 2x/20
=> x=8
so, 3x = 24

divide 100 by 7, and you get 14.28. (Obviously you aren’t talking about decimals here) and so 14 numbers can be divisible by 7 up to 100.

The answer is 14.

360 years old
Nepo’s son age = x
Nepo’s age = 3x
Nepo’s father age = 2*3x + 40

x + 3x + 6x + 40 = 1240
10x = 1200
x = 120

Nepos age = 3* 120 = 360 years
