W1 10rs
w2 14rs
w3 16rs
then total mixture is 110kg
and correspondingly the total price is 1540.....
So wheat per kg is 1540divided by 110 that is equal to 14.......

Vignesh   12 years AGO

Rate of 20kg of 10rs wheat = 20*10 = 200rs
Rate of 5okg of 14rs wheat = 50*14 = 700rs
Rate of 40kg of 16rs wheat = 40*16 = 640rs
Mixture of all the three= Total rupees/Total kg's
= 200+700+340/20+50+40
= 1540/110
= 14rs per kg.

20 kg. of 10 Rs. --> 20*10 = 200
50 kg. of 14 Rs. --> 50*14 = 700
40 kg. of 16 Rs. --> 40*16 = 640

Total cost is 200+700+640 = 1540
Total Kg is 20+50+40 = 110

Cost of mixture = 1540/110 = 14 ...
