Consider the simple interest of the following

(A) The simple interest on Rs 8,930 at 6% per annum for 5 years

(B) The simple interest on Rs 3,080 at 13.50% per annum for 4 years

(C) The simple interest on Rs 7,200 at 14.00 % per annum for 7 years

(D) The simple interest on Rs. 3,120 at 4.00 % per annum for 5 years

The simple interests of these in increasing order are:

Choose the correct answer from the options given below:

The simple interest formula is:

$SI = \dfrac{P \times R \times T}{100}$

where $P$ is the principal, $R$ is the rate per annum, and $T$ is the time in years.

---

For option (A): Principal $= Rs \space 8,930$, Rate $= 6\%$, Time $= 5$ years

$SI = \dfrac{8,930 \times 6 \times 5}{100}$

$SI = \dfrac{267,900}{100}$

$SI = Rs \space 2,679$

---

For option (B): Principal $= Rs \space 3,080$, Rate $= 13.50\%$, Time $= 4$ years

$SI = \dfrac{3,080 \times 13.50 \times 4}{100}$

$SI = \dfrac{166,320}{100}$

$SI = Rs \space 1,663.20$

---

For option (C): Principal $= Rs \space 7,200$, Rate $= 14\%$, Time $= 7$ years

$SI = \dfrac{7,200 \times 14 \times 7}{100}$

$SI = \dfrac{705,600}{100}$

$SI = Rs \space 7,056$

---

For option (D): Principal $= Rs \space 3,120$, Rate $= 4\%$, Time $= 5$ years

$SI = \dfrac{3,120 \times 4 \times 5}{100}$

$SI = \dfrac{62,400}{100}$

$SI = Rs \space 624$

---

Comparing the simple interests:

(D) $Rs \space 624$

(B) $Rs \space 1,663.20$

(A) $Rs \space 2,679$

(C) $Rs \space 7,056$

Therefore, the simple interests in increasing order are: (D), (B), (A), (C)
