Jerry went to a shop and bought things worth Rs. 35, out of which 30 % went on sales tax on taxable purchases. If the tax rate was 6%, then what was the cost of the tax free items?
[ "19.7", "29.7", "21.3", "21.5" ]
B
Total cost of the items he purchased = Rs.35 Given that out of this Rs.35, 30 % is given as tax => Total tax incurred = 30 % = Rs.30/100 Let the cost of the tax free items = x Given that tax rate = 6% ∴ (35−30/100−x)6/100 = 30/100 ⇒ 6(35 −0.3 −x) = 30 ⇒ (35 − 0.3 − x) = 5 ⇒ x = 35 − 0.3 − 5 = 29.7 E)

To fill a tank, 25 buckets of water is required. How many buckets of water will be required to fill the same tank if the capacity of the bucket is reduced to two-fifth of its present ?
[ "62.5", "64", "65", "60" ]
A
Let the capacity of 1 bucket = x. Then, the capacity of tank = 25x. New capacity of bucket = 2/5 x Therefore, Required number of buckets = (25x)/(2x/5) = (25x) x 5/2x = 125/2 = 62.5 Answer is A.
