Answer»

Work done by A and B in 12 DAYS is = 12 * 5/120 = 1/2

Therefore REMAINING work = 1- 1/2 = 1/2work

B does 1/40 work in one day

Therefore B does 1/2 work in 40*1/2 =20days

Work done by A and B in 12 days is = 12 * 5/120 = 1/2

Therefore Remaining work = 1- 1/2 = 1/2work

B does 1/40 work in one day

Therefore B does 1/2 work in 40*1/2 =20days
