**The following pie-chart shows the market share of different banks in India. Based on this pie-chart determine the questions given below.**

### Question 1.

**If the value of the market share of BOI is Rs. 4000 crores, then the market share of BOB and Axis bank together is **

**A.** 24,363 crores**B.** 24,432 crores**C**. 24,864 crores**D**. 25, 827 crores

**Explanation :**

You can see that BOI accounts for 11 % of the market share. And this 11 % is equal to the 4000 crores. So to calculate the total market share of BOB and axis the formula will be, 67/11 x 4000 = 24,363. Thus, the correct answer is A.

### Question 2.

**If the total market share other than Axis and BOB is Rs. 335,000 crores. Then find the market share of BOI and HDFC banks.**

In addition to this the other banks that are left accounts for 33 % which equates to 35,000 crores. HDFC and BOI equal the market share of 27 %. Thus, their market share in terms of crores is 27 x 335000/33 => 274090 crores. So, the correct answer is C.

### Question 3.

**A**. 1: 2**B.** 3: 1**C**. 1 : 3**D.** Not possible

**Explanation :**

Take the market share of BOB and BOI and compare them both to find the ratio. As a result, the market share of BOB is given as 34 % and the market share of BOI is given as 11 %. So, the ratio of market share of BOI to a market share of BOB will be 11: 34. This will be close to 1 : 3. So, the correct answer is C.
