ATQ,
Let the original usage be ‘x’ units and the price per unit be Rs. ‘y’.
Initial expenditure = Rs. xy
New increased price = Rs. 1.10y
Reduced usage = 0.95x
New expenditure = 1.10y × 0.95x = Rs. 1.045xy
Hence, the expenditure increases by 4.5%.
(44.85% of 639.79 + 3/8 of 480.23) × (√63.84 – 19.99% of 499.71) = ?
`[(sqrt(750) xx15.981) -: 54.003]` `xx` ? = 6997.81001
? = 460.24 + 1057.97 – 14.992
15.1 + 3.97 – 9.07 × 1.96 = √?
Find the value of ‘x’ in the given expression:[144 + {2 × (13 ÷ 0.5 × 6 – 3) ÷ 4} – 6.5] = x
? * 9.34 = (275.09 ÷ 8.89) % of 5125 - 1150.88
14.742 ÷ 24.98 × 15.76 = ?% of 359.88
√65 of 14.97 + √50 = (12.02)2 - ?
What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)...
2.51% of 800 - 3.97% of 250 = ?
