Answer:Step-by-step explanation:
The price of pure coconut oil is 200 per litre
A shopkeeper adulterates it with some other types of oil at 100 per litre
Let say Ratio mixed in A : B
Cost Price = 200A + 100B Rs
Total Mixture = A + B litre
Selling Price = 192(A + B) Rs
Gain = 192(A + B) - (200A + 100B)
= 92B - 8A Rs
Gain % = 40 %
Gain = (40/100) * (200A + 100B)
= 80A + 40B
92B - 8A = 80A + 40B
=> 52B = 88A
=> A /B = 52 /88
=> A / B = 13/22
=> A :B = 13 : 22
Hence none of these
Step-by-step explanation:
Answer:
none of these , as 13: 22 is ratio in which he mixed the two oil
Step-by-step explanation:
The price of pure coconut oil is 200 per litre
A shopkeeper adulterates it with some other types of oil at 100 per litre
Let say Ratio mixed in A : B

Gain = 192(A + B) - (200A + 100B)
= 92B - 8A Rs
Gain % = 40 %
Gain = (40/100) * (200A + 100B)
= 80A + 40B
92B - 8A = 80A + 40B
=> 52B = 88A
=> A /B = 52 /88
=> A / B = 13/22
=> A :B = 13 : 22
Hence none of these
