heya dear user
here is ur answer

let the no of hen be x
let the no of eggs be y
let the no of bananas be z
now here ,
according to first equation

x + x+ x = 60
3 x = 60
x = 20

so here , hen is equal to 20

now in second equation

20 + y + y = 26
2y = 26- 20
2y = 6
y = 3

so eggs are 3

now in third equation
3 + z + z = 15
3 + 2z = 15
2z = 15 - 3
2z = 12
z = 6

now number of bananas is 6

then here , in fourth equation
adding hen + banana × eggs , we get
20 + 3 × 6 = 35

so the answer is 35

hope it helps

PrincessNumera: But when u multiply 3*5 = 35 then there u should plus 20 also
LonelyHeart: u need to use BODMAS rule na
LonelyHeart: 20+3×6
PrincessNumera: yes first u multiply and the add
PrincessNumera: ohhhhhhhhhhh
PrincessNumera: sorrry
PrincessNumera: i thought its 5 :Stuck_out_tongue

Hey friend,
Here is your answer:

First we will substitute the value of
• Hen as A.
• Eggs as B.
• Banana as C.
• ??? as D.

Hence, the value of Hen is:
» A + A + A = 60
» 3A = 60
» A = 60/3
» A = 20

Hence, the value of Eggs is:
» A + B + B = 26
» A + 2B = 26
» 2B = 26 - 20
» 2B = 6
» B = 6/2
» B = 3

Hence, the value of Banana is:
» B + C + C = 15
» B + 2C = 15
» 3 + 2C = 15
» 2C = 15 - 3
» 2C = 12
» C = 12/2
» C = 6

But in the last equation, there are 5 bananas in the bunch.
∴ A + B × C = D
» 20 + 3 × 5 = D
» D = 20 + 15
» D = 36

♦ Hence, 35 is your answer.

Hope it helps u.

LonelyHeart: ya yr
Shanaya200: please tell where is a mistake in my answer so i can correct it
LonelyHeart: π_π full confusion yr
LonelyHeart: where did I go wrong?
Shanaya200: hehe
