A) 1
B) 2
C) 4
D) 10
Correct Answer: C
Solution :
The number inside the circle is obtained by multiplying the sum of the upper number, the lower number and the number corresponding to the position of the letter in the English alphabet, multiplying by the number on the right and then subtracting the number on the left from the product. Thus we have \[\left( 2+C+5 \right)\times 3-4=(2+3+5)\times 3-4=26;\] \[\left( 4+H+4 \right)\times 5-10=(4+8+4)\times 5-10=70.\] Let the missing number be x. Then \[(8+4+6)\times x-6=90\] \[\Rightarrow (8+10+6)\times x=96\Rightarrow x=4.\]
