The sum of four consecutive multiples of 4 is 200. What is the largest number?

A 48

B 52

C 56

D 60

Solution

Correct Answer: Option C

ধরি,
চারটি ক্রমিক 4 এর গুণিতক যথাক্রমে x, (x + 4), (x + 8) এবং (x + 12)

প্রশ্নমতে,
x + (x + 4) + (x + 8) + (x + 12) = 200
⇒ 4x + 24 = 200
⇒ 4x = 200 - 24
⇒ 4x = 176
⇒ x = 176/4
⇒ x = 44

∴ বৃহত্তম সংখ্যা = x + 12 = 44 + 12 = 56
