Ayesha khatoon  (9 years ago)

answer is A..3.62
for first 30 kg l so
according to the question,
ffor 33 kg apple
30l+3Q=11.67....
and for 36 kg apple
30l+6q=12.48......(2)
by solve these two we get 3Q=.81
and so 30l=11.67-.81=10.86,
10L=3.62

A. 3.62

30L+6Q=12.48 ....(1)
30L+3Q=11.67 ....(2)

(1)-(2)=> Q=0.27. Substitute it in (1) or (2) 10L=3.62

Padmaja.G  (9 years ago)

33kg of apples = 11.67
36kg of apples = 12.48
36kg-33kg = 3 kg
12.48-11.67 = 0.81
so 3kg of apples = 0.81
now consider 33 kg (30 + 3), now 30 kg of apples = 11.67-0.81
= 10.86
therefore 30 kg = 10.86
10 kg = (10*10.86)/30 = 3.62
(i.e) 10 kg of apples = Rs 3.62

anurag jain  (9 years ago)

ans is = 3.62(appox.)
the rate of 33 kgs= 33L+3Q=11.67
the rate of 36 kgs= 36L+6Q=12.48
then 30L= 10.84
the rate of 10 kgs 10L=3.62

Is this solution Helpfull? Yes (1) | No   

udhayakumarie  (9 years ago)

ans:3.62
36-33=3 kg
12.48-11.67=8.7
so that 30 kgs=10.80
10 ks =3.62

vivek  (9 years ago)

30L+3Q=11.67
30L+6Q=12.48
Solving these two equations,
Q=.81
10L=3.62

3.62 is ans

Is this solution Helpfull? Yes | No   

AMIY SRIVASTAVA  (9 years ago)

ans) a
value of q=(12.48-11.67)/3=.27p
now cost of 30 apple=cost of 33 apple-3*q=11.67-(3*.27)=10.96
therefore cost of 10 apple=10.96*10/30=3.62

Is this solution Helpfull? Yes | No   

saumya shukla  (9 years ago)

for every other 3 kg price = 12.48 - 11.67 = 0.81.

Let x is price for every 1 kg before 30.

Hence price for 33kg Apple is:-
Hence for, 30x + 0.81 = 11.67
30x = 10.86
3x = 10.86/3 = 3.62

Is this solution Helpfull? Yes | No
