Conditions :
- The number of guests attended the dinner was one - third of the members
- Each guests paid rs.400 and each members paid rs.300 and the total collection was Rs.104000
46. According to question
- x = number of members
- y = numbers of guests
According to the first condition, The number of guests attended the dinner was one - third of the members. So, the equation will be
- y = x/3
- y - x/3 = 0
- 3y - x = 0 Option d
47. According to the second condition, Each guests paid rs.400 and each members paid rs.300 and the total collection was Rs.104000
→ 400y + 300x = 104000
→ 100(4y + 3x) = 104000
→ 4y + 3x = 1040 Option b
48. Let's solve both above equations
- 3y - x = 0 --(i)
- 4y + 3x = 1040 ---(ii)
Multiply (i) by 3
- 9y - 3x = 0
Add equations
→ 9y - 3x + 4y + 3x = 0 + 1040
→ 13y = 1040
→ y = 1040/13 = 80. Option a
49.
Substitute the value of y in eqⁿ (i)
→ 3y - x = 0
→ 3 × 80 - x = 0
→ 240 - x = 0
→ x = 240. Option c
50.
Total expenditure incurred in arranging dinner = Rs.122000
Sum of collection for the event = Rs.104000
Club has to spent money = (122000-104000) = Rs.18000. Option c
Step-by-step explanation:
given :
- 46. If the number of members attended the dinner is and the number of guests is "then the equation for the first condition is:
- 47. if number of members and guests remains X and y respectively, then the equation for the second
- 48. How many guests attended the party?
- 49. How many members attended the party?
- 50. If the total expenditures incurred on arranging the dinner was Rs 1,22,000. how much money the club has to spend?
to find :
- 46. then the equation for the first condition is = ?
- 47. X and y respectively, then the equation for the second = ?
- 48. guests attended the party = ?
- 49. how much money the club has to spend = ?
solution :
46. ans :
x and number of guest is y equation for first
condition = 3 y - x = 0 D option correct
47 ans :
x and y respectively, then the equation for the second condition = 4 y + 3x = 1040
b option is correct
48 ans:
guests attended for the party = 80
49. ans :
- members attended the party = 240 members
