Q.) If the product of the integers a, b, c and d is 3094 and if 1 < a < b < c < d, what is the product of b and c?

(a) 26

(b) 91

(c) 133

(d) 221

Solution :

3094 can be expressed as 2 X 7 X 13 X 17

Now the condition given is 1 < a < b < c < d

and from the above 2<7<13<17

Hence , a = 2 , b= 7 ,c=13, d=17

product of 7X13 = 91

Hence , Option(b)
