Answer»

<P>⇒ Let the ratio of employees in 3 branches initially be 7p, 5p and 8p.

⇒ Given (7p + 400)/(5p + 400) = 15/11

⇒ So, 75p + 6000 = 77p + 4400

⇒ 2P = 6000 - 4400 = 1600

⇒ On SOLVING, we get p = 800

∴ Initial number of employees in 3 offices together = 7p + 5p + 8p = 20p = 20 × 800 = 16000
