To find Rana's investment and change in his annual income, we need to break down the given information and calculate step by step.

1. Rana bought 500 shares of HCL at a rate that yielded him a 20% return on a 24%, Rs 350 share.
- The investment in HCL shares can be calculated by multiplying the number of shares (500) by the cost per share (Rs 350): 500 * 350 = Rs 175,000.
- The 20% return on investment means he gained 20% of the invested amount: 20/100 * 175,000 = Rs 35,000.

2. The company issued a bonus share for every 10 shares held.
- Since Rana held 500 shares, he received a bonus of 500/10 = 50 shares.
- Now he has a total of 500 + 50 = 550 shares.

3. When the market price was Rs 480, Rana sold all the shares.
- The total amount received from selling the 550 shares is 550 * 480 = Rs 264,000.

4. Rana invested the proceeds in buying Rs 300 shares of IBM paying a dividend of 27.5%.
- The investment in IBM shares can be calculated by dividing the total amount received (Rs 264,000) by the cost per share (Rs 300): 264,000 / 300 = 880 shares.
- The annual income from the dividend can be calculated by multiplying the number of shares (880) by the dividend rate (27.5/100): 880 * (27.5/100) = Rs 242.

5. The yield percent on Rana's investment now is 25%.
- The yield percent can be calculated by dividing the annual income from the dividend (Rs 242) by the investment amount (Rs 264,000) and multiplying by 100: (242 / 264,000) * 100 = 0.092 * 100 = 9.2%.

Therefore, Rana's investment is Rs 264,000, and there is a change in his annual income of Rs 242.
