ANSWERS WITH EXPLANATION:
- BWD
- Triangle
- 120
[Hint: Find the LCM of 8, 12 and 15] - 751
- 6
[Hint: LCM x HCF = Product of the numbers] - 8
[Hint: Let 5 consecutive numbers be x, x+1, x+2, x+3, x+4
Given x + x+ 1+ x+ 2 + x + 3 + x + 4 = 50
5x + 10 = 50
5x = 40
x = 40/5 = 8] - 42925
[Hint: Sum of the squares of first n natural numbers = n (n + 1) (2n + 1) /6] - 8.008
- 9975
[Hint: 105 x 95 = (100 + 5) (100 – 5)] - 500
[Hint: Let the number be x
30% of x = 50% of 300]
