Options

A. `(i)to(Q),(ii)to(R),(iii)to(S),(iv)to(P)`
B. `(i)to(R),(ii)to(P),(iii)to(S),(iv)to(Q)`
C. `(i)to(R),(ii)to(S),(iii)to(P),(iv)to(Q)`
D. `(i)to(Q),(ii)to(S),(iii)to(P),(iv)to(R)`

Explanation

To solve the problem of matching the expressions in Column I with their corresponding results in Column II, we will go through each expression step by step.

### Step 1: Solve the first expression
**Expression:** \( 715 + 12.59 + 685.35 \)

1. **Add 715 and 685.35:**
\[ 715 + 685.35 = 1400.35 \]

2. **Now add 12.59:**
\[ 1400.35 + 12.59 = 1412.94 \]

**Result:** \( 1412.94 \) matches with \( R \).

### Step 2: Solve the second expression
**Expression:** \( 518 - (216.80 - 115.96) \)

1. **Calculate the subtraction inside the brackets:**
\[ 216.80 - 115.96 = 100.84 \]

2. **Now subtract this result from 518:**
\[ 518 - 100.84 = 417.16 \]

**Result:** \( 417.16 \) matches with \( P \).

### Step 3: Solve the third expression
**Expression:** \( 4.090 + 0.050 + 6.500 \)

1. **Add 4.090 and 0.050:**
\[ 4.090 + 0.050 = 4.140 \]

2. **Now add 6.500:**
\[ 4.140 + 6.500 = 10.640 \]

**Result:** \( 10.640 \) matches with \( S \).

### Step 4: Solve the fourth expression
**Expression:** \( 36.050 + 198.05 - 21.03 \)

1. **First, add 36.050 and 198.05:**
\[ 36.050 + 198.05 = 234.1 \]

2. **Now subtract 21.03:**
\[ 234.1 - 21.03 = 213.07 \]

**Result:** \( 213.07 \) matches with \( Q \).

### Final Matching
- (i) \( 715 + 12.59 + 685.35 = R \) (1412.94)
- (ii) \( 518 - (216.80 - 115.96) = P \) (417.16)
- (iii) \( 4.090 + 0.050 + 6.500 = S \) (10.640)
- (iv) \( 36.050 + 198.05 - 21.03 = Q \) (213.07)

### Summary of Matches
- First part (i) matches with R
- Second part (ii) matches with P
- Third part (iii) matches with S
- Fourth part (iv) matches with Q
