If 9685 is divided into three parts in such a way that one - fourth of the first part, one - third of the second part and one- dicth of the third part are equal, then what is the first part?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 2980
Let the first part, second part and third part be a, b and c respectively.
⇒ a/4 = b/3 = c/6 = y
⇒ a = 4y, b = 3y and c = 6y
⇒ a + b + c = 9685
⇒ 4y + 3y + 6y = 9685
⇒ y = 745
The first part of number = a = 745 × 4 = 2980
