Question

M + J = 24 days
J + v= 30 days
V+ m= 40 days
m+J+v=?​

Answer 1

2m + 2j + 2v = 94

(2) m + j + v = 94

m + j + v = 94/2

m + j + v = 47

Answer 2

Answer:

m+j+v=47

Step-by-step explanation:

We have, m+j=24

-> m= 24 - j -(1)

••••••••••••••••

Next, we have, v+m=40

-> v + 24 - j = 40 [from (1)]

-> v - j = 40 - 24

-> v - j = 16

-> v = 16 + j -(2)

••••••••••••••••

Now, we have, j + v = 30

-> j + 16 + j = 30 [ from (2)]

-> 2j = 30 - 16

-> j = 14/2

-> j = 7 -(3)

•••••••••••••••

So, m + j = 24

m + 7 = 24 [ from (3)]

m = 24 -7

m = 17 -(4)

•••••••••••••••••

And, v + m = 40

v + 17 = 40 [ from (4)]

v = 40 - 17

v = 23 -(5)

•••••••••••••••••

Therefore, from 3,4 and 5:-

m+j+v= 17+7+23 = 24+23 = 47
