-
- 3m+4a=85...(i)
5a+6p=122....(ii)
6m+2p=114....(iii)
after solving (i) & (ii),we get the eqn in terms of m & p i.e
15m-24p=-63....(iv)
now, we solve eqn(iii) & eqn(iv),we get
m=15,a=10,p=12 - 11 years agoHelpfull: Yes(35) No(8)
- I think there is typing mistake in qn.
If statement is
3 mangoes and 4 apples costs Rs 85. 5 apples and 6 peaches costs Rs. 122. 6 mangoes and '3' peaches cost Rs.114. what is the combined price of 1 apple, 1peach and 1 mango?
then
3M+4A+0P=85
0M+5A+6P=122
6M+0A+3P=144
adding these eqns
9(M+A+P)= 351
M+A+P= 351/9=39 ... option (b)

- ans 37.
3m+4a=85....(1)
5a+6P=122....(2)
6m+2p=114....(3)
solving i and 2 and 3 we'll get 37 - 11 years agoHelpfull: Yes(13) No(3)
- 3m+4a=85...(i)
5a+6p=122....(ii)
6m+2p=114....(iii)
Adding (i) (ii) (iii) we get
9a+9m+8p= 321
9a+9m+9p= 321+p
a+m+p=(321+p)/9------(iv) It must have to be a integer number.
To make (iv) as an integer p must have to be either 3 or (3+9) or (3+18)or.....
Let check it out..
if p=3 then
5a+18=122
5a=104
a!= an integer so p=3 is false
If a=12, then
by(ii)
5a=122-72
a=10
by(i)
3m=85=40
a=15
a+m+p= 15+10+12=37.

- Let x b mango cost, y b apple cost, z b peaches cost.
3x+4y=85----eq1
5y+6z=122-----eq2
6x+2z=144----eq3
by solvin above equations v get x=15,y=10,z=12
so combined price--> 15+10+12=37

- from the question
3m+4a=85---->1
5a+6p=122---->2
6m+2p=114----->3
solve 1 and 3
we get 8a-2p=56.let it be 4th eq.
now solve 4 and 2.
29a=290
a=10.from 4,by substituting a,we get p=12.
substitute a,p in eq3.we get m=15
now a+b+c=10+12+15=37.

- 3m + 4a = 85 ..(1)
5a + 6p = 122 ..(2)
6m + 2p = 144 ..(3)
(1) x 2 => 6m + 8a = 170
4 x (3) => 6m + 2p = 144
Solving we get 8a - 2p = 56 ..(4)
(2) => 5a + 6p = 122
3 x (4) = 24a - 6p = 168
Solving we get a = 10, p = 12, m = 15
So a + p + m = 37 - 10 years agoHelpfull: Yes(1) No(0)

- 3M + 4A = 85....eq1
5A + 6P = 122...eq2
6M + 2P = 114...eq3
sub eq3 by 2*eq1
=> 8A - 2P = 56....eq4
sub eq2 by 3 * eq4
29A = 290
=> A = 10
put value of A in 1st and 2nd eq
M = 15
P = 12
now, A + P + M = 10 + 12 + 15 = 37 answer - 3 years agoHelpfull: Yes(0) No(0)
