**Solution:**

We have to match each of the entries in Column I with the appropriate entries in Column II.

(i) 3:5

In percentage, 3:5 = 3/5 × 100

= 3(20)

= 60% (E)

(ii) 2.5

In percentage, 2.5 × 100 = 250% (H)

(iii) 100%

Ratio = 100/100 : 1

= 1 : 1

Multiplying by 3 on both sides,

= 3 : 3 (O)

(iv) 2/3

In percentage, 2/3 × 100

= 200/3

= 66 2/3 % (J)

(v) 6 1/4 %

6 1/4 = 25/4%

In fraction, (25/4) / 100 = 25/400 = 1/4 (G)

(vi) 12.5%

In fraction, 12.5/100 = 0.125 (L)

(vii) SP when CP = ₹50 and loss = 6 %

SP = 50 - 6% of 50

= 50 - (6/100) × 50

= 50 - 6/2

= 50 - 3

SP = ₹47 (B)

(viii) SP when CP = ₹50 and profit = ₹4

We know, Profit = SP - CP

4 = SP - 50

SP = ₹54 (A)

(ix) Profit% when CP = ₹40 and SP = ₹50

Profit = SP - CP

= 50 - 40

= ₹10

Profit% = Profit/CP × 100

= 10/40 × 100

= 100/4

= 25% (F)

(x) Profit% when CP = ₹50 and SP = ₹60

Profit = SP - CP

= 60 - 50

= ₹10

Profit% = Profit/CP × 100

= 10/50 × 100

= 100/5

= 20% (K)

(xi) Interest when principal = ₹800, Rate of interest = 10% per annum and period = 2 years

We know, I = P × R × T/100

I = 800 × 10 × 2 / 100

= 8 × 20

= ₹160 (D)

(xii) Amount when principal = ₹150, Rate of interest = 6% per annum and period = 1 year

We know, I = P × R × T/100

I = 150 × 6 × 1 / 100

= 15 × 6/10

= 3 × 3

= ₹9

We know, A = P + I

A = 150 + 9 = ₹159 (I)
