Answer:
Ball = Rs 100 ✬
Step-by-step explanation:
Given:
Cost of 7 bats and 6 balls is Rs 13200.
Cost of 3 bats and 5 balls is Rs 5900.
To Find:
What is the cost of each bat and ball ?
Solution: Let the cost of each bat and ball be Rs x and y respectively.
➙ Cost of 7 bats = Rs 7x
➙ Cost of 6 balls = Rs 6y
\implies{\rm }⟹ 7x + 6y = 13200
Equation 1
Now , In second case
➙ Cost of 3 bats = Rs 3x
➙ Cost of 5 balls = Rs 5y
\implies{\rm }⟹ 3x + 5y = 5900
Equation 2
[ Multiplying 5 in equation 1 and 6 in equation 2 ]
➯ (7x + 6y) 5 = 13200 × 5
35x + 30y = 66000ㅤㅤㅤeqⁿ i
➯ (3x + 5y) 6 = 5900 × 6
18x + 30y = 35400ㅤㅤeqⁿ ii
ㅤㅤㅤㅤㅤ35x + 30y = 66000
ㅤㅤㅤㅤㅤ18x + 30y = 35400
ㅤㅤㅤㅤㅤ–ㅤㅤ–ㅤㅤ–
ㅤㅤㅤㅤ━━━━━━━━━━━━━━━
ㅤㅤㅤㅤㅤ17x = 30600
∴ x = 30600/17 = 1800
Now putting the value of x in equation 1.
\implies{\rm }⟹ 7 × 1800 + 6y = 13200
\implies{\rm }⟹ 6y = 13200 – 12600
\implies{\rm }⟹ y = 600/6
\implies{\rm }⟹ y = 100
Hence, the cost of each bat and ball is Rs 1800 & Rs 100 respectively.
