Find the single discount rate percentage equivalent to the successive discounts of 10%, 20% and 20%.
Effective Discount = 1 -(1-0.10) (1-0.20) (1 - 0.20) =1- (0.90 × 0.80 × 0.80) = 1- 0.576 = 0.424 Convert to Percentage- Single Discount Rate = 0.424 × 100 = 42.4% The equivalent single discount rate is 42.4%.
√10201 × √3969 - (52)² = √? + (60)²
...2852 + 7848 + 2962 + 4268 = ? – 1460
(25 + 12) x 6 + 34 = ? + 18
9/5 × 18/25 ÷ 42/21 = ? - 82/75
32 × 3 (54 – 15) + 186 ÷ 3 ÷ 2 – (21)² =?
The alarms of two alarm clocks sound at regular intervals of 72 seconds and 80 seconds. If they beep together for the first time at 6:00 am, at what tim...
56 × 18 + ? × 21 – 49 × 12 = 63 × 26
{18 × 5 + 48 ÷ 8} × 8 = ? + 684
22% of 280 + 34% of 1080 × 5/12 =? + 16% of 460
16 × ? + 36% of 250 = 410
