Answer with explaination..​

Answer 1

       $\text{\huge \underline{Answer:}}$

       $\text{Amount of rice purchased by farmer} = 100 \text{ kg}$

       $\text{Amount of pulses purchased by farmer} = 50 \text{ kg}$

       $\text{Cost of 1 kg rice} = \text{Rs. 15}$

       $\text{Cost of 1 kg pulses} = \text{Rs. 20}$

$\implies \text{Cost of 100kg rice} = \text{(Cost of 1 kg rice)(100)}$

$\implies \text{Cost of 100kg rice} = (15)(100) = \text{Rs. }1500$

$\implies \text{Cost of 50 kg pulses} = \text{(Cost of 1 kg pulses)(50)}$

$\implies \text{Cost of 50 kg pulses} = (20)(50) = \text{Rs. 1000}$

$\implies \text{Total money spent} = 1500 + 1000 = \text{Rs. }2500$

       $\text{Amount of money the farmer had} = \text{Rs. 3000}$

$\implies \text{Money left with him} = (\text{Amount he had}) - (\text{Total money spent})$

$\implies \text{Money left with him} = 3000 - 2500 = \text{Rs. 500}$

 $\therefore \text{ \:}\boxed{\boxed{\text{The money left with him after the purchase} = \text{Rs. 500}}}$
