ESE 2018 GS Paper Solution The 12 digits on the face of a clock are to be represented employing contributions of only the number 9 as either 9 or /9 prescribed conditions are (i) the least number of uses alone are permitted; and (ii) whe alternates are possible, use of preferred over use of V9, which should be used minimally. How many times would V9 have to be used ? 94. . The other sible, of 9 will be 6 (b) 5 (c) 4 (d) 3 a.

Ans. b) Example: 1 = 9/9, 2-9+9/9, 3-V9, 4-v9 +9/9. 5-N9+ 9+9 /9 '6= 9-v9 , 7= 9-949/9, 8-9-9/9, 9e9, 10-9+ 9/9, 11=9+ 9+9/9 , 12-9+ 9

Ans. d) A+B= 100, C+D= A, B= 4D, D= C-10, C= D+10, A= 2D+ 10, A+4D 100. Solving the equations you will get the value of C which is 25.
