Question

the cost of 5¼ kg of apple is ₹336. what is the rate of apple per kg?​

Answer 1

Answer:

Given, the cost of \(5\frac {1}{4}=\frac {21}{4}\ kg\) apples is \(Rs\ 336\). Hence, the rate of apples per kg is \(Rs\ 64\).

Answer 2

$\: \: \sf{cost \: of \: \: 5¼ \: \: kg \: of \: apple = ₹336}$

$\: \: \sf{cost \: of \: 1 \: kg \: of \: apple \: = 336 \div 5 \frac{1}{4} }$

$\: \: \: \: ⇢ \: \: \: \: \: \: \: \: \: \: 336 \div \frac{21}{4}$

$\: \: \: \: \: \: \: \: \: ⇢ \: \: \: \: \: \sf{ \cancel{336} \times \frac{4}{ \cancel{21}}}$

$\: \: \: \: \: \: \: \: \: \: \: \: \ ⇢ \: \: \: \sf{16 \times {4}}$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: ⇢ ₹ 64$
