Sandy and Mandy do (8/13)th part of a work and the rest of the work was completed by Andy. If Sandy, Mandy and Andy take the same work for Rs 2600, then what is the share (in Rs) of Andy? Correct Answer 1000

Given:

Sandy and Mandy do (8/13)th part of a work.

The rest of the work was completed by Andy.

Sandy, Mandy and Andy take the same work for Rs 2600.

Formula used:

W = E × T     Where, W = Work, E = Efficiency, and T = Time

Calculation:

Let the amount of total work be a

Work done by Sandy and Mandy = 8a/13

Work done by Andy = a – 8a/13 = 5a/13

Total amount of money taken by the 3 people = Rs. 2600

⇒ Andy’s share = 2600 ×

⇒ Andy’s share = Rs. 1000

∴ The share (in Rs) of Andy is 1000.
