The cost of type A cement is ₹100/kg and that of Type B cement is ₹120/kg. If both are mixed in the ratio of 2 : 3, the price of the cement mixture per kg will be :

₹112

The correct answer is Option (3) → ₹112

$T_{total}$, Calculating the total cost for 5 kg,

Total cost of type - A cement = 2 × 100 = 200

Total cost of type - B cement = 3 × 120 = 360

$∴T_{total}=(200+360)$

$=560$

$∴T_{1kg}=\frac{560}{2}=112$
