**Dear BA'ians,**

**The most awaiting post of the day as you all wanted to practice the D.I. question based on today's exam pattern, so here it comes.

(2) 9/91

(3) 18/455

(4) 2/5

(5) None of these

**11.If 2 balls are picked at random, what is the probability that both are blue?**

(1) 1/5

(2) 8/91

(3) 2/15

(4) 2/27

(5) None of these

**12.If 4 balls are picked at random, what is the probability that 2 are red and 2 are green?**

(1)4/15

(2)5/27

(3)1/3

(4)2/455

(5)None of these

**Answers :**

**1.5;Cost price of V = Rs.50**

Transportation cost = Rs.30

Total cost price = 50+30=Rs.80

Profit = 4%

Selling price = 80*104/100 = Rs.83.2

2.2; Selling price of X = (Cost price + Cost on transportation + Profit) = 250+20+5=275

Cost price of W =Selling price + Loss

= 100+10=Rs.110

Required % = 275*100/110%

=250%

3.4; Loss on Y = Cost price of Y - selling price of Y

= 400*100/96-400 =416.66-400 = Rs.16.66

Loss on W = Rs.10

Reqd ratio = 16.66:10=833:500

4.3; Selling price of Z = Cost price of Z+Cost on transportation + Profit

=400+40+440*6/100= Rs.466.4

Selling price of X =Rs.275

Difference =466.4-275=Rs.191.4

5.3; Selling price of V = (Cost price + Cost of Transportation)*95/100=

(50+30) *95/100 = Rs.76

Selling price of Z = Rs.466.4

Reqd% = (466.4-76)*100/466.4

=83.7%
