The price of six different commodities for year 2009 and year 2011 are as follows:
| Commodities | A | B | C | D | E | F |
| Price in 2009 (₹) | 35 | 80 | 25 | 30 | 80 | x |
| Price in 2011 (₹) | 50 | y | 45 | 70 | 120 | 105 |
Answer & explanation
Correct answer: option 1
The correct answer is option (1) : 60
$∑p_0= 35+80+25+30+80+x=360$
$250+x=360$
$x=110$
$∑p_1= 50+y + 45+70+120+105=390+y$
Now, $\frac{390+y}{360}×100= 125$
$390+y = \frac{125×36}{10}$
$y = 60$
