Question
Find the ratio of total number of black pens sold by B
and C to total pens (Red + Black) sold by A. Read the following data carefully and answer the following questions: The table shows the total number of Pens (Red + Black) sold by three shops A, B and C. It also shows the percentage of unsold Pens (Red + Black) and number of Red pens sold by shopkeepers.Solution
Total number of pens sold by B = 75% of 600 = 450 Total number of black pens sold by B = 450 – 190 = 260 Total number of pens sold by C = 60% of 800 = 480 Total number of black pens sold by C = 480 – 80 = 400 total number of pen sold by A = 400×50/100 =200 Required ratio = (260 + 400) : 200 = 660:200 = 33:10
- (√ 196 x √ 36 x √ 100) = ?% of 200 
- What will come in place of the question mark (?) in the following questions? 
 
 
 25% of 360+40=?
- (5832) 2/3 / (104976)3/4 X ? = ( `sqrt(18)` ` ` ) 5 ...
- Solve the following: - 523 + 523 x 523 ÷ 523 
- If 28957.5 ÷ 268.125= 108, then 289.575 ÷ 2681.25 is equal to: 
- 666(2/3)% of 30 - 116(2/3)% of 90 =? 
- 2(1/3) + 2(5/6) – 1(1/2) = ? – 6(1/6) 
- Find the value of ‘y’ if (2/7) × y = 0.79 – 1.77 ÷ 3. 
- 82% of 400 + √(?) = 130% of 600 - 85% of 400
