Question

A and B polished of floors of building in 6 days. A can do 1/4 of it in 6 days in how many days B alone polish floors​

Answer 1

a can do 1/4 in 6 days.

Thus, b can do 3/4 in 6 days.

Thus, b alone can do polish in

3/4 * b = 6

b = 6*4/3

b = 8 days

Answer 2

Answer:

8

Step-by-step explanation:

$part \: of \: work \: done \: in \: 6 \: days = 1 \\ part \: of \: a = \frac{1}{4} \\ so \: part \: of \: b = 1 - \frac{1}{4 } = \frac{3}{4} \\ hence \: b \: can \: do \: \frac{3}{4} th \: of \: work \: in \: 6 \: days \\ hence \: to \: do \: ( \frac{3}{4} \div \frac{3}{4} ) = 1 \: part \: of \: work \: b \: will \: require \: (6 \div \frac{3}{4} ) \: days \\ = 6 \times \frac{4}{3} \: days \\ = 2 \times 4 \: days \\ = 8 \: days$
