64
48
43
24
11
Correct answer is A
first term[a] = 3 * d → 3 * 8 = 24
sixth term of the A.P = a + 5d → 24 + [5 * 8]
⇒ 24 + 40 = 64
Divide the LCM of 15abc and 20a\(^2\)bc by their HCF
10a
12a
5abc
12a2bc
60a2bc
Correct answer is B
LCM of 15abc and 20a\(^2\)bc = 60a\(^2\)bc
Factors of 15abc = 1, 3, 5,15, a, b, c
and of 20a\(^2\)bc = 1, 2, 4, 5, 10, 20, a, b, c
HCF of 15abc and 20a\(^2\)bc = 5abc
→ LCM ÷ HCF = 60a\(^2\)bc ÷ 5abc
= 12a
