5.
A dozen bananas costs Rs.20. What is the price of 48 bananas?
1.
| Number of letters | 738 | x |
| Shortout time (in hours) | 6 | 9 |
Since the given data are in direct proportion.
\(\frac{738}{6}=\frac{x}{9}\)
6x = 738 x 9
\(x=\frac{738 \times 9}{6}=1107\)
1107 letters can be sorted in 9 hours.
2.
| Height of the pole (m) | 8 | x |
| Height of the shadows (m) | 6 | 30 |
Since the given data are in direct proportion,
\(\frac{x_{1}}{y_{1}}=\frac{x_{2}}{y_{2}}
\)
\(\frac{8}{6}=\frac{x}{30}
\)
6x = 8 x 30
\(\therefore x=\frac{8 \times 30}{6}\)
x = 40 m
If the height of the shadow is 30 m height, then the height of the pole is 40 m.
3.
| Number of trips | 8 | 12 |
| Number of people | 120 | x |
Since the given data are in direct proportion
\(\frac{x_{1}}{y_{1}}=\frac{x_{2}}{y_{2}}\)
\(\frac{8}{120}=\frac{12}{x}\)
8x = 120 x 12
\(\therefore x=\frac{120 \times 12}{8}=180\)
In 12 trips, 180 people would have attended the party.
4.
Rs. 840 paid for 21 students.
Rs. 1680 (double of its amount) paid for 42 students (double the students).
5.
One dozon banana cost = Rs. 20
i.e.,12 bananas cost = Rs. 20
I banana cost \(=Rs\ \frac{20}{12} \)
48 bananas cost \(=\frac{20}{12} \times 48 \)
= Rs. 80
