1/2*I= 1*(1/2)+2(1/4)+3(1/8)+.. eqn 2<br />

http://thegatebook.in/qa/1636/q22-talent-test?show=1725#a1725
Let the original price = Rs x/kg <br />
Reduced price =79/100x /kg <br />
==> 100/(79x/100) - 100/x = 10.5 <br />
==> 10000/79x - 100/x = 10.5 <br />
==> 10000 - 7900 = 10.5 * 79 x <br />
==> x = 2100/10.5*79 <br />
So required price = Rs (79/100*2100/10.5 *79) /kg <br />
= Rs 2 per kg.Aptitudehttp://thegatebook.in/qa/1636/q22-talent-test?show=1725#a1725Tue, 11 Apr 2017 15:07:43 +0000Answered: Q21 Talent Test

http://thegatebook.in/qa/1615/q1-talent-test?show=1709#a1709
Why not both B & C?. C: Always looks at a easy question. The question setter himself says that "He always looks a easy question". So initially "Ram is confident to get fee concession" so if he always looks a easy question(he may be well talented/prepared/whatever reason ) then he will stay in the first state only while leaving the exam hall.<br />
<br />
Note: A question may not be tough for every one.Toughness is relative. So as the C option says if he always looks a easy question he will leave confident.Aptitudehttp://thegatebook.in/qa/1615/q1-talent-test?show=1709#a1709Mon, 10 Apr 2017 07:49:30 +0000Answered: Question 19 answer not given?
