Question
Amit is offering two consecutive discounts on a
smartphone marked priced at Rs. 18,000. The final selling price is Rs. 12,420 after applying the first discount of 8%. Determine the percentage of the second discount provided by Amit.Solution
The first discount percentage offered = 8% Let, the second discount percentage offered be 'd'% Total discount percentage offered = [(18000 - 12420) /18000] × 100 = 31% If two successive discounts of 'c'% and 'd%' are offered, then total effective discount percentage offered = c + d - (cd/100) Total discount offered = 8 + d - {(8 × d/100) } = 8 + d - [(8 × d) /100] = 31 Or, 8 + 0.92d = 31 Or, 0.92d = 23 Or, d = 25
187 ÷ 5 ÷ 0.4 = ? – 24 × 2.4
Find the simplified value of the given expression:
(125 - 75 ÷ 3 of 5) ÷ 2 + 4 of 12 ÷ 3 - 16 of 5 ÷ 20
70 % of 640 + 75 % of 360 - 19 × 12 = ?
- Find the simplified value of following expression:
0.998 + 0.882 + 0.12 (√1296 – 12) × 5 = ? + 40
?% of (168 ÷ 8 × 20) = 126
458.32-563.32+659.32=?
`sqrt(5476)` + 40% of 1640 = ? `xx` 4 - 2020
[(40)2 ÷ 32 × 4] ÷ 50 = ?
