Question 9 REVISIT fa group of 5 actresses and 3 junior artists can complete 23 episodes in 4 days, Whereas 2 actors or 3 junior artists can complete 7 episodes in 2 days, then how many actresses should help 7 junior artists so that they can complete 45 episodes in 6 days?​

Answer 1

Solution :-

Let , actresses is denoted by A and junior artists is denoted by J .

So,

→ (5A + 3J) makes episodes in 4 days = 23

→ (5A + 3J) makes episode in 1 day = (23/4) .

also,

→ 2A makes episodes in 1 day = (7/2) = 3J makes episodes daily .

then,

→ 3J makes episodes in 1 day = (7/2)

→ 1J makes episodes in 1 day = (7/6)

→ 7J makes episodes in 1 day = (49/6) episodes.

therefore,

→ 7J makes episodes in 6 days = (49/6) * 6 = 49 episodes .

As we can see that, 7J makes more than 45 episodes in 6 days .

Hence, we can conclude that, 7 junior artists dont need help of any actress to complete 45 episodes in 6 days .
