1.

**Ans. C.****10% of the total expenses was spent on**

**Clothing**

**Amount spent on Clothing = $2500**

**3% of the total expenses was spent on**

**Favors**

**Amount spent on Favors= $750**

**50% of the total expenses was spent on**

**Catering and venue**

**Amount spent on Catering and venue =**

**$12500**

**Average amount spent**

**= (2500+750+12500)/3**

**Average amount spent = $ 5250**

**Hence the correct option is option (C).**

**Alternate way:**

**% of budget spent on Clothing =10**

**% of budget spent on Favours =3**

**% of budget spent on Catering and**

**venue = 50**

**Adding all three we get**

**% of budget spend on Clothing, favour**

**and catering and venue=10+3+50=63**

**Avg budget spend on Clothing, favour**

**and catering and venue= (1/3) *63% of**

**25000 =5250**

**2. Ans. B.**

**10% of the total expenses comprised of**

**Photography costs.**

**∴ Money spent on Photography**

**∴ Money spent on Photography = $2500**

**Hence the correct option is option (B).**

**3. Ans. A.**

**1% of the total expenses comprised of**

**Transportation costs.**

**∴ Money spent on Transportation**

**= 1/100 * 25000**

**∴ Money spent on Transportation =**

**$250**

**3% of the total expenses comprised of**

**Favors costs.**

**∴ Money spent on Favors = 3/100 * 25000**

**∴ Money spent on Favors = $750**

**∴ Required ratio = 250/750 = 1/3**

**∴ Required ratio = 1 : 3**

**Hence the correct option is option (A).**

**Alternate way :**

**% of budget spent on Transportation=1**

**% of budget spent on Favours =3**

**Required Ratio - % of budget spent on**

**Transportation : % of budget spent on**

**Difference = 12500 - 3250 = $ 9250**

**Hence the correct option is option (E).**

**5. Ans. B.**

**50% of the total expenses was spent on**

**Catering and venue**

**Amount spent on Catering and venue =**

**10% of the total expenses was spent on**

**Decorations**

**Amount spent on Decorations = $2500**

**2% of this is to be spent extra.**

**Money saved = 1500 - 50 = $ 1450**

**Hence the correct option is option (B).**
