Question

If 10 men or 20 boys can make 260 mats in 20 days, then 8 men and 4 boys will make how many mats in 20 days ?
(A) 260
(B) 240
(C) 280
(D) 520

Answer 1

Answer:

option A(260)

Step-by-step explanation:

10 men = 20 boys

→1 men = 2 boys

8 men = 2 × 8 boys = 16 boys

Then,

(16 boys + 4 boys) = 20 boys can make 260 mats in 20 days

Now,

It can be calculated by work equivalence method:

20 × 260 × 20 = x × 20 × 20

x = 260 mats

Answer 2

Answer:

a:-260

Step-by-step explanation:

[m1×t1×d1÷w1=m2×t2×d2÷w2]

10m×20days÷260mats=20b×20days÷260mats

10m=20b

1m=2b

m/b=2/1

1m work=2units/ day

1b work=1 units/ day

mats made by 8m+4b in 20 days

10m×20days÷260mats=(8m+4b)×20days÷xmats

10×2×20days÷260=20×20days÷xm

x=260 mats
