Select the correct option.
A) 56  B) 65  C) 73  D) 89  E) 90
A + B + C = 3 *50= 
<gadget id="calculator">3 *50</gadget>
<output>150</output>
150   A + B + C + D= 4 * 53= 
<gadget id="calculator">4 * 53</gadget>
<output>212</output>
212 ---- (i)   So, D= 62&amp; E = 62 + 3= 
<gadget id="calculator">62 + 3</gadget>
<output>65</output>
65   B + C + D +E= 51 * 4= 
<gadget id="calculator">51 * 4</gadget>
<output>204</output>
204 --- (ii)   From Eq. (i) &amp; (ii)   A-E= 212 – 204 = 8   A = E +8 = 65 + 8= 
<gadget id="calculator">65 + 8</gadget>
<output>73</output>
