From statement 1:
Work done by A in 1 day =
Work done by B in 1 day =
Work done by C in 1 day = 1 / 15
Work done by A, B and C in 1 day = (
) + (
) + (
)
⇒
Statement 1 alone is not sufficient to answer the question.
From statement 2:
Difference between the wages of B and C is Rs 320
Statement 2 alone is not sufficient to answer the question.
But from statement 1 and statement 2,
Wages of A, B and C together =
() × (165 + 120 + 88)
⇒ 10 × 373
⇒ 3730
∴ Statement 1 and 2 together is needed to answer the question.
