Answer:
At least 3 bags will be required to pack the fruit in equal amount.
Step-by-step explanation:
Given:
Number of apples she buys =15
Number of oranges she buys = 18
Number of mangoes she buys = 21
we need to find the least possible number of bags used.
Solution:
To find the least possible number of bags required we will find the prime common factor.
Multiples of 15 =
Multiples of 18 =
Multiples of 21 =
so we can say that;
Highest common prime factor in all three numbers is 3.
Hence At least 3 bags will be required to pack the fruit in equal amount.

10m-p=-n
10m-p+p=-n+p
10m=p-n devide by 10
m=(p-n)/10
Answer:
(3, 10 ) and (7, 30 )
Step-by-step explanation:
Given the 2 equations
5x - y = 5 → (1)
2y - x² = 11 → (2)
Rearrange (1) expressing y in terms of x
y = 5x - 5 → (3)
Substitute y = 5x - 5 into (2)
2(5x - 5) - x² = 11
10x - 10 - x² = 11 ← rearrange into standard form
x² - 10x + 21 = 0 ← in standard form
(x - 3)(x - 7) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 3 = 0 ⇒ x = 3
x - 7 = 0 ⇒ x = 7
Substitute these values into (3) for corresponding values of y
x = 3 → y = 5(3) - 5 = 15 - 5 = 10 ⇒ (3, 10 )
x = 7 → y = 5(7) - 5 = 35 - 5 = 30 ⇒ (7, 30 )
