The avg weight of A,B & C is 60 kg. If D joins the group, the avg weight of the group becomes 65 kg.If another man E who weights is 3 kg more than D Replaces A, Then the avgof B,C,D&E becomes 64 kg. What is the weight of A?  Pick.
A) 56 B) 65 C) 75 D) 89 E) 87
A + B + C = 3 *60= 
<gadget id="calculator">3 *60</gadget>
<output>180</output>
180   A + B + C + D= 4 * 65= 
<gadget id="calculator">4 * 65</gadget>
<output>260</output>
260 ---- (i)   So, D= 80&amp; E = 80 + 3= 
<gadget id="calculator">80 + 3</gadget>
<output>83</output>
83   B + C + D +E= 64 * 4= 
<gadget id="calculator">64 * 4</gadget>
<output>256</output>
256 --- (ii)   From Eq. (i) &amp; (ii)   A-87= 260 – 256 = 4   A = 87 +4 = 83 + 4= 
<gadget id="calculator">83 + 4</gadget>
<output>87</output>
