Step-by-step explanation:

a+b=1/30 after working for 23 days then

a+b=23/30 then remaining work is 7/30 this work A alone work for (33-23) 10days

then A alone do full work 300/7 then B alone do the work 1/30-7/300=3/300 = 1/100

B alone do the work in 100 days

Answer:

A+B- 30DAYS

A - TAKE 7 DAYS WORK - 10 DAYS

DIFFERENCE - 3 DAYS

FOR 30 DAYS WE NEED MULTIPLY WITH 10

A= 7*10 =70

B = 10*10 = 100 Days
