If there is 22400 rupee expense of 14 men for 8 days then how many expense of 7 men for 13 days? please explain thanks
sweet-ann [11.9K]

Answer:

The expense of 7 men for 13 days is 18,200 Rs.

Step-by-step explanation:

The expense of 14 men for 8 days = 22400

The expense of 14 men per day = 22400/8 = 2800

The expense of 1 man per day = 2800/14 = 200

The expense of 7 men per day = 200*7 = 1400

The expense of 7 men for 13 days = 1400*13 = 18200

Help please! I do not exactly understand how to do this. Thanks!
Radda [10]

X and Y are supplementary, that means X + Y = 180.

But we have, X  = Y +24, then

X + Y = Y + 24 + Y = 2Y + 24 = 180

Then

2Y = 156

Y = 78

Then X = 78 + 24 = 102.
