Question

How many numbers lying between 20 and 200 are divisible by 4? 1. 43 2. 44 3. 45 4. 46

KnowledgeBoat · Accepted Answer

The numbers divisible by 4 lying between 20 and 200 form an Arithmetic Progression (A.P.). 24, 28, ....., 196. a = 24 l = 196 d = 4 Let no. of terms be n. We know that, nth term of A.P. : ∴ Tn = a + (n - 1)d ⇒ 196 = 24 + (n - 1)4 ⇒ 196 - 24 = (n - 1)4 ⇒ 172 = (n - 1)4 ⇒ = n - 1 ⇒ 43 = n - 1 ⇒ n = 43 + 1 ⇒ n = 44. Hence, option 2 is the correct option.
