Answer 2

Answer:

The amount earned by 20 men and 24 women in 10 days is Rs.1640.

Step-by-step explanation:

It is given that 8 men or 15 women earn 1200 in 30 days, i.e.,

The total amount earned by 8 men or 15 women in 30 days = Rs.1200

The total amount earned by 8 men or 15 women in 1 day = 1200/30

                                                                                               = Rs.40

So,

The amount earned by 1 men in a day = 40/8

                                                                = Rs.5

Thus, the amount earned by 20 men in a day = 5 $\times$ 20

                                                                             = Rs.100

The amount earned by 1 women in a day = 40/15

                                                                     = Rs.8/3

Thus, the amount earned by 24 women in a day = $\frac{8}{3} \times 24$

                                                                                  = 8 $\times$ 8

                                                                                  = Rs. 64

Now,

The amount earned by 20 men and 24 women in a day = 100 + 64

                                                                                              = Rs.164

Thus, the amount earned by 20 men and 24 women in 10 days is,

= 164 $\times$ 10

= Rs.1640
