First discount is of 29% and second discount is of 13%.

Therefore, according to question:

X = 1000

Time taken by experienced carpenter = 8 days

Time taken by young carpenter = 12 days

Lcm (12, 8) = 96 units

1 day work of experienced carpenter = 96/8 = 12 units

1 day work by young carpenter = 96/12 = 8 units

Total number of days they work together = 3 days

3 day work by (A + B ) = 3 (12 + 8 ) = 3( 20 ) = 60 units

Left work = 96 – 60 = 36 units

Then young carpenter leaves and the work is completed by experienced carpenter alone.

Time taken by experienced carpenter to complete the work = 36/12 = 3 days
