The avg weight of A,B & C is 55 kg. If D joins the group, the avg weight of the group becomes 60 kg.If another man E who weights is 3 kg more than D Replaces A, Then the avgof B,C,D&E becomes 58 kg. What is the weight of A? Select:
A) 56
B) 65
C) 75
D) 86
E) 90
A + B + C = 3 *55= 
<gadget id="calculator">3 *55</gadget>
<output>165</output>
165   A + B + C + D= 4 * 60= 
<gadget id="calculator">4 * 60</gadget>
<output>240</output>
240 ---- (i)   So, D= 75&amp; E = 75 + 3= 
<gadget id="calculator">75 + 3</gadget>
<output>78</output>
78   B + C + D +E= 58 * 4= 
<gadget id="calculator">58 * 4</gadget>
<output>232</output>
232 --- (ii)   From Eq. (i) &amp; (ii)   A-E= 240 – 232 = 8   A = E +8 = 78 + 8= 
<gadget id="calculator">78 + 8</gadget>
<output>86</output>
