If C=3 and CAT=24, what is FAULT?

Answer: (a) 60 

Solution:-
The place value of C = 3, 
The place value of A = 1, 
The place value of T = 20. 
Then, the sum of the place values of CAT = 3 + 1 + 20 
 = 24

Same as, 
The place value of F = 6, 
The place value of A =1, 
The place value of U = 21, 
The place value of L = 12, 
The place value of T = 20. 
Then, the sum of the place values of FAULT = 6 + 1 + 21 + 12 + 20
 = 60. 

Hence, the correct answer is option (a) 60.
