<output>16</output>
16 years   So, total age of two women= 35 + 45 +16= 
<gadget id="calculator">35 + 45 +16</gadget>
<output>96</output>
96   Average age of two women=96/2= 
<gadget id="calculator">96/2</gadget>
<output>48</output>
48 years   3(d) Total decrease= 20 * 2= 
<gadget id="calculator">20 * 2</gadget>
<output>40</output>
40 month= 3 years 4 month   So, age of new boy = 18 years – 3 years 4 month   = 14 years 8 month   14 years 8 month
