Answer:
15 days
Step-by-step explanation:
P = 30 * 2/1 = 60 DAYS (P can complete ½ of a job, so remaining job ½)
.•. S = 10 * 2/1 = 20 DAYS
NOW
LCM of P(60) and S(20) work ie. 60 ( ie total work which will be done )
P total work 60. so 1 day work of P 60/60 = 1
S total work 20. so 1 day work of S 60/20 = 3
total work of P and S 1 + 3 = 4
.•. total days for complete 60 works is 60/4 = 15 days
