Write a letter to your father about the progress in your studies and request him to increase your monthly allowance.

Letter

I revived your letter a few days ago. I was happy to read it. I am sorry for the late reply as I was busy with the examination. I am well and hope that you will also be well. I want to tell you that I have passed December test in good marks. I have got 80% marks in English and math. I have stood first in my class and maintained my position. My expenses have increased very much due to dearness. I have to cut down my expenses on necessary things. I have bought some books of English and Math. They have emptied my pocket. The money that you send is not enough to me due to dearness. Please increase Rs.5000\- in my monthly allowance. I hope that you will grant it happily. 
pay regards to all.
