Let the rate of second quality be Rs x per Kg.
C.P of 1Kg wheat of 1st kind = 930p
C.P of 1 Kg wheat of 2nd kind = 100x p
Mean price = 1000p
By rule of alligation we have required ratio 8 : 7

930 x



/

(Mean Price)
(10)

/



x-10 : 0.7 :: 8 : 7

So we get required ratio, (x-10) : 0.7 :: 8 : 7
⇒ x = 10.80 per Kg
