Answer» Total Number of employees = 100 Ratio of number of directors, SUBJECT e x perts and INTERNS = 1 : 2 : 7 ∴ Number of directors = 10 Number of subject e x perts = 20 Number of interns = 70 Ratio of entrance tickets = 2 : 3 : 5 ⇒ Total ticket costs = (10 x 2) + (20 x 3) + (70 x 5) = 430 When Total amount = Rs 430, interns pay (70 x 5) = Rs 350 ∴ When total amount = 1720, amount paid by interns = $(\frac{{1720}}{{430}}\; \times 350\; = \;Rs\;1400)$

Answer»

Total Number of employees = 100

Ratio of number of directors, SUBJECT e x perts and INTERNS = 1 : 2 : 7

∴ Number of directors = 10

Number of subject e x perts = 20

Number of interns = 70

Ratio of entrance tickets = 2 : 3 : 5

⇒ Total ticket costs = (10 x 2) + (20 x 3) + (70 x 5) = 430

When Total amount = Rs 430, interns pay (70 x 5) = Rs 350

∴ When total amount = 1720, amount paid by interns = $(\frac{{1720}}{{430}}\; \times 350\; = \;Rs\;1400)$
