Question

If a + b= 29 , b + c = 45, a + c = 44Find a + b + c = ?

Answer 1

a + b= 29

b + c = 45

a + c = 44

Add all the three,

(a + b) + (b + c) + (a + c) = 29 + 45 + 44

=> 2a + 2b + 2c = 118

=> 2(a + b + c) = 118

=> a + b + c = 118/2

=> a + b + c = 59


Required answer is 59.

Answer 2

ᴀᴅᴅ ᴀʟʟ ᴛʜᴇ ᴛʜʀᴇᴇ
ᴀ+ʙ+ʙ+ᴄ+ᴀ+ᴄ=29+45+44
2(ᴀ+ʙ+ᴄ)=118
ᴀ+ʙ+ᴄ=118/2
ᴀ+ʙ+ᴄ=59
