The avg weight of A,B & C is 80 kg. If D joins the group, the avg weight of the group becomes 82 kg.If another man E who weights is 3 kg more than D Replaces A, Then the avgof B,C,D&E becomes 81 kg. What is the weight of A?  Pick one:
A) 56 B) 65 C) 75 D) 89 E) 95
A + B + C = 3 *80= 
<gadget id="calculator">3 *80</gadget>
<output>240</output>
240   A + B + C + D= 4 * 82= 
<gadget id="calculator">4 * 82</gadget>
<output>328</output>
328 ---- (i)   So, D= 88&amp; E = 88 + 3= 
<gadget id="calculator">88 + 3</gadget>
<output>91</output>
91   B + C + D +E= 81 * 4= 
<gadget id="calculator">81 * 4</gadget>
<output>324</output>
324 --- (ii)   From Eq. (i) &amp; (ii)   A-95= 328 – 324 = 4   A = 95 +4 = 91 + 4= 
<gadget id="calculator">91 + 4</gadget>
<output>95</output>
