​​​​​​​​​​​​​​

Due to overrun in ‘design’, the design stage took 3 months, i.e. months 3, 4 and 5. The number of people working on design in the fifth month was 5. Calculate the percentage change in the cost incurred in the fifth month. (Due to improvement in ‘coding’ technique, this stage was completed in months 6-8 only.)

Answer & solution

Correct answer: 150%

  • A

    225%

  • 150%

  • C

    275%

  • D

    240%

Solution

Originally for the fifth month, 4 people were scheduled to do coding. This would have cost them (10000 × 4)
= Rs. 40,000. Now there are 5 people who are working on design in the fifth month.
The total cost for this would be (20000 × 5) = Rs.1,00,000.
Hence, percentage change in the cost incurred in the fifth month = (100000 40000)40000× 100 = 150%
