“Two hundred rupees,” the man said. “It has saved more careers than the university’s placement office.”
Years later, Arslan became a finance manager at a textile mill. In his office, behind the framed degree and the photo of his parents, there is a worn-out, dog-eared, blue book.
The final exam arrived. Arslan saw a tough question on Bill Discounting. He didn't panic. He didn't try to recall the Key . Instead, he heard the voices of Mirza & Mirza in his head—not giving him the answer, but teaching him the formula.
“Bhai saab,” he mumbled to the shopkeeper, “I need the solution. Not the textbook. The Key .” Key Book Of Business Mathematics By Mirza And Mirza
“Read it. But don’t worship the answer. Respect the journey. Mirza & Mirza didn't make you a mathematician. They made you a survivor.”
Arslan bought it instantly.
Then came the midterms.
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.
He passed with a B+.
Humiliated, Arslan went back to the book bank. The old man was there, still smoking. “Two hundred rupees,” the man said
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.
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.
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. The final exam arrived
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.
