**1. Question :**

Find the value of a for which a+5, 3a-10 and 2a+a/2 are in AP

**Correct Answer:**

10

**Explanation:**

Since a+5, 3a-10 and 2a+a/2 are in AP, we have

2(3a-10)=(a+5)+(2a+a/2)

6a-20=a+5+2a+a/2

6a-20=(6a+a)/2+5

12a-40=7a+10

12a-7a=10+40

5a=50

a=10

**2. Question :**

A retailer buys 25 items from a wholesaler. The total price for which the flawless items were sold was equal

to the price that he had paid for buying the 25 items and 20% of the items were defected. Find the gain percent

of the retailer.

**Correct Answer:**

25%

**Explanation:**

Number of items purchased=25

Defected items=20/100*25

=500/100=5

Let the cost price of each item be Rs.x

Total cost price=25x

Number of items bought=25

Total selling price=25x

Number of items sold=25-5=20

Gain%=[(25x/20-25x/25)/25x/25]*100

=(25x-20x)/20x*100

=25%

**3. Question :**

Find the sum of all two-digit natural numbers that are divisible by 4.

**Correct Answer:**

1188

**Explanation:**

The smallest and the largest such numbers are 12 and 96

The numbers form an AP with common difference d=4 and the first term a=12

The last term is 96 and let there be n terms in the AP

nth term is given by

Tn=a+(n-1)d

96=12+(n-1)4

96=12+4n-4

88=4n

n=88/4=22

Sum of n terms is given Sn=(n/2)[2a+(n-1)d]

=(22/2)[2*12+(22-1)4]

=11(24+21*4)

=11(24+84)

=11*108=1188

The sum of the required numbers is 1188
