In May, John bought the same amount of rice and the same amount of wheat as he had bought in April, but spent $₹150$ more due to price increase of rice and wheat by $20\%$ and $12\%,$ respectively. If John had spent $₹450$ on rice in April, then how much did he spend on wheat in May $?$

1. $₹580$
2. $₹570$
3. $₹560$
4. $₹590$

Let the price of rice in April be $₹x,$ and the price of wheat in April be $₹y.$

TABLE

Now,

$1 \cdot 2x + 1 \cdot 12y = 150 + x + y$

$\Rightarrow \frac{12}{10}(450) + 1\cdot 12y = 150 + 450 + y$

$\Rightarrow 540 + 1 \cdot 12y = 600 + y$

$\Rightarrow 1 \cdot 12y – y = 600 – 540$

$\Rightarrow \frac{12}{100}y = 60$

$\Rightarrow 12y = 60 \times 100$

$\Rightarrow \boxed{ y = 500}$

So, money spend on wheat in May $= 1 \cdot 12y = \frac{112}{100} \times 500 = ₹560$

$\therefore$ The money spends on the wheat in May is $₹560.$
