The correct answer is A. Rs. 60,532.
The sales budget for May 20XX is Rs. 55,000. Of this, 40% is expected to be for cash, which is Rs. 22,000. The remaining 60% is expected to be on credit, of which 70% is expected to be paid in the month after sale and take a 2% discount. This means that 0.7 * 0.6 = 42% of the sales budget for May 20XX is expected to be received in May. This is equal to Rs. 23,100. The remaining 28% of the sales budget for May 20XX is expected to be received in the second month after sale. This is equal to Rs. 15,450. Therefore, the total value of sales budget to be shown in the cash budget for May 20XX is Rs. 22,000 + Rs. 23,100 + Rs. 15,450 = Rs. 60,532.
