Choose the correct choice from the following choices:
A) 3.69	B) 3.66	C) 3.6	D) 150	E) 3.61
Ans: By framing equations we get   30L+3Q=333   30L+6Q=366   Eliminate Q by multiplying the first equation by 2 and subtracting second equation from the first   60L+6Q =666   30L+6Q =366   30L = 300 =&gt; L = 10   Then we get L =10   Cost of 15 kgs of apples =15 x 10 = 150   Answer:150
