A dishonest shopkeeper seels hand sanitizer at cost price but he mixes water and earns (50/3)%. Find the ratio between the total amount of mixture to the amount of hand sanitizer?

let cost price be C
ratio of milk and water be M:W
acoording to the condition total selling amount of the (M+W)litre of milk at C rupee = (M+W)*C
and total cost of purchasing= M* C
according to the conditon given -; (M+W)*C= 7/6*M*C
6M+6C= 7M
M/C= 6/1
6:1
