HERE'S THE ANSWER...

____________________________

▶️ Making equations first..

♠️ A can do a piece of work in 20 days

⏺️  __( 1 )

♠️ B do that work in 15 days

⏺️  __( 2 )

♠️ Now A and B together do a work

⏺️ Adding eqn ( 1 ) and ( 2 )

=>  

⏺️ L.C.M. = 60

=>  

=>  

♠️ They worked together from 6 days

=>  

=>  

♠️ If A left and remain work had to be done by B

=> Remaining work = 1 - 7 / 10

=>  

♠️The B will take to complete the remaining work

= 10/3 × 1/15

=> 10/45

♠️ So B will complete it in

=> 45/10

=> [ 4.5 days ]✔️✔️✔️

=> 2
