Explanation:-
Solution:
Mango Packing rate of Ram Lal =
707$$\frac{70}{7}$$
= 10 per hour
Guavas Packing rate of Ram Lal =
567$$\frac{56}{7}$$
= 8 per hour
Mango Packing rate of Ram Lal's Wife =
306$$\frac{30}{6}$$
= 5 per hour
Guavas Packing rate of Ram Lal's Wife =
246$$\frac{24}{6}$$
= 4 per hour
On comparing,
8 Guavas = 10 Mangoes
1 Guavas =
108$$\frac{10}{8}$$
Mangoes
2400 Guavas =
10×24008$$\frac{10\times 2400}{8}$$
= 3000 Mangoes
This means that they need to pack (6300 + 3000) Mangoes
Combined Mango Packing rate of Both = 10 + 5 = 15 per hour
We will take 2 days = 1 time unit.
Working 10 hours a day they will pack 150 Mangoes in 1 time unit
Total time taken to pack 6300 Mangoes =
6300150$$\frac{6300}{150}$$
= 42 time unit
So, total time taken = 2 × 42 = 84 days
