Question

The price of $7$ bananas is equal to the cost of $3$ kiwis. The price of $2$ kiwis is equal to the cost of $1$ banana and $5$ chikoos. If Rambo has just enough money to buy $30$ chikoos, then how many bananas Rambo could buy with the same amount?

• A. $22$
• B. $20$
• C. $25$
• D. $11$

Answer 1

Answer: (A)

$22$

$7B=3K$
$2K=B+5C$
Putting $K=\frac{7}{3}$B in $(2K=B+5C)$
$2\left(\frac{7}{3}B\right)=B+5C$
$\frac{14B}{3}-B=5C$
$\frac{11B}{3}=5C$
$22B=30C$ in Rs. $30$ he can buy $22$ Banana.
