Answer:

teri ma ka tailor bhsdika

Answer 2

Answer :-

→ Tailer stitches in 16 days = 5 dress .

→ Tailer stitches in 1 day = (5/16) dress .

similarly,

→ His son stitches in 20 days = 6 dress .

→ Tailer stitches in 1 day = (6/20) = (3/10) dress .

then,

→ Both stitches per day = (5/16) + (3/10) = (5*5 + 8*3)/80 = (25 + 24)/80 = (49/80) dress .

therefore,

→ Both stitches (49/80) dress in = 1 day .

→ Both stitches 1 dress in = 1/(49/80) = (80/49) day .

→ Both stitches 49 dress in = (80/49) * 49 = 80 days (Ans.)
