Question : Directions: In a code language, DENT is written as 51, and LOAD is written as 40. How will COST be written in that language?
Option 1: 75
Option 2: 62
Option 3: 65
Option 4: 57
Correct Answer: 65
Solution :
Given:
DENT is written as 51, and LOAD is written as 40.
Add 8 to the sum of the positional value of the letters of DENT, to obtain the required code –
(D(4) + E(5) + N(14) + T(20)) + 8 = 43 + 8 = 51
Thus, DENT is coded as 51.
And, LOAD is coded as 40 –
(L(12) + O(15) + A(1) + D(4)) + 8 = 32 + 8 = 40
Thus, LOAD is coded as 40.
Similarly, follow the same pattern for COST –
(C(3) + O(15) + S(19) + T(20)) + 8 = 57 + 8 = 65
Thus, COST is coded as 65. Hence, the third option is correct.
