Indian electricity prices have risen from  Rs 6.4 to Rs 6.5 per unit. Arvi's factory expected to use 600 units in the next billing period. He installed solar panels at the start of that period. This reduced his electricity usage by 90%.?
How much did Arvi's bill increase?
1) 6
2) 38
3) 39
4) 54

Answer :

tanishqsingh
the increase per unit=rs 0.1
increase in 600 units=rs.60
90% is reduced 
⇒54 is reduced 
so actual increase=60-54=6
So the answer is 1) 6
