Correct Answer: 3 : 7
Solution : Let's assume that the ratio in which the two types of sugar are mixed is $x:y$ The cost of sugar of Rs. 30 per kg is 30$x$ The cost of sugar of Rs. 40 per kg is 40$y$ The mixture is worth Rs. 37 per kg So, the cost of the mixture is $37(x+y)$ ⇒ $30x + 40y = 37(x+y)$ ⇒ $40y − 37y = 37x − 30x$ ⇒ $3y = 7x$ ⇒ $y$ : $x$ = 3 : 7 Hence, the correct answer is 3 : 7.
