Read the following hypothetical text and answer the given questions:
Amit and Mahesh were partners in a fast-food corner sharing profits and losses in ratio 3:2. They sold fast food items across the counter and did home delivery too. Their initial fixed capital contribution was ₹1,20,000 and ₹80,000 respectively. At the end of first year their profit was ₹1,20,000 before allowing the remuneration of ₹3,000 per quarter to Amit and ₹2,000 per half year to Ranju. Such a promising performance for the first year was encouraging, therefore, they decided to expand the area of operations.
For this purpose, they needed a delivery van, a few Scotties and an additional person to support. Six months into the accounting year they decided to admit Sundram as a new partner and offered him 20% as a share of profits along with a monthly remuneration of ₹2,500. Sundram was asked to introduce ₹1,30,000 for capital and ₹70,000 as premium for goodwill. Besides this Sundram was required to provide ₹1,00,000 as loan for two years. Sundram readily accepted the offer. The terms of the offer were duly executed and he was admitted as a partner.
While taking up the accounting procedure for this reconstitution the accountant of the firm Mr. Suraj Marwah faced a difficulty. Solve it by answering the following: For the amount of loan that Sundram has agreed to provide, he is entitled to interest thereon at the rate of____________.
