His teacher, Professor Tariq, wrote formulas on the blackboard like a poet reciting verses, but to Arslan, they were hieroglyphics. After failing his first class test, he decided to visit the famous bookshop.
In the sweltering heat of a Multan summer, the only cool place Arslan knew was the shaded corner of Al-Faisal Book Bank. He was a first-semester student of B.Com, and his heart sank lower than his grades every time he looked at the syllabus. Business Mathematics wasn't just a subject; to him, it was a dragon with three heads—Profit & Loss, Annuities, and the dreaded Matrix Inversion.
When a junior intern asks him how to understand compound proportion, Arslan doesn’t explain. He simply hands over the book and says:
He passed with a B+.
For the first month, Arslan cheated. He copied the solutions directly into his homework notebook. He didn’t understand why you multiplied the annuity by (1+i), but he knew the Key said so. His homework scores shot up from 3/10 to 9/10. Professor Tariq raised an eyebrow but said nothing.
Humiliated, Arslan went back to the book bank. The old man was there, still smoking.
“Beta,” he said softly. “This is not a Key to open the exam door. It is a Key to open your mind. Mirza and Mirza didn't write this so you could copy. They wrote it so you could compare . You do the sum yourself, sweat over it, bleed over it, then open the Key to see if you are correct. You used it backward.” Key Book Of Business Mathematics By Mirza And Mirza
Arslan walked into the exam hall, confident. He flipped the paper. Question one: “A person buys a washing machine for Rs 25,000 on a 10% flat interest rate over 3 years. Find the installment.”
“Read it. But don’t worship the answer. Respect the journey. Mirza & Mirza didn't make you a mathematician. They made you a survivor.”
He froze. His brain was empty. He had memorized the answer from the Key , but he had never learned the path . He saw the numbers swimming on the page. He tried to recall page 124, exercise 7(b), question number 11. But the steps were gone. He failed the midterms miserably. His teacher, Professor Tariq, wrote formulas on the
Slowly, painfully, the fog lifted. Logarithms became friends. Break-even points became visible. The word “Annuity” stopped sounding like a disease and started sounding like a paycheck.
That night, Arslan did something radical. He covered the right side of every page with a ruler. He took out a blank register and attempted every single problem on his own. Only when he was stuck—really stuck—did he peek at Mirza & Mirza’s solution.
“This book is a liar!” Arslan shouted, slamming the blue Key on the counter. “I copied everything and still failed!” He was a first-semester student of B
The old shopkeeper, smoking a cigarette that hung permanently from his lip, didn't even look up. He slid a thick, blue-bound book across the glass counter. The title was embossed in gold: Key Book of Business Mathematics – Mirza & Mirza .
Arslan bought it instantly.
