Q.1. Solve the image
' x='0' y='0' height='100%25' width='100%25' xlink%3Ahref='data%3Aimage/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAcAAAAHCAIAAABLMMCEAAAAY0lEQVQImTVOCQ7AIAjz/z9V0Rgv8Iqrc2sCIS2Uqr33nJOZY4zoay0wCpVzZpaUUikF82H7C601WUvkIIwxFK5qre4HZhE5u9CNMegwgcPZvb7eeyIKIUD7viFDaw0ZcHszPIvhjVtmIuzHAAAAAElFTkSuQmCC'%3E%3C/image%3E%3C/svg%3E)
- 125
- 185
- 156
- 625
Clearly, ( 52-32 )= 16, ( 122-82 )= 80, ( 342-272 )= 427,So missing number is: ( 212-162 )= 185,. So answer is (b) option.
Q.2. If a shopkeeper gives 25% discount, he still earns 25% profit. If he now gives 10% discount then what is the profit percentage he gains?
Marked Price=100
After discount price = 75
Profit is 25% so Cost price = 60
If they give 10% discount, then Price = 90
Profit % = (30/60) x 100 = 50%
Q.3. There are as many four-legged chairs and as many four-legged tables as workers in the office of Yamraj, and as many three-legged stools as four-legged almirahs. If the number of stools be one more than number of workers and the total number of legs be 585,then what is the number of workers in the office?
4 legged chairs = 4 legged tables = number of workers.
3 legged stools = 4 legged almirahs
No. of stools = 1 + no. of workers
Total no. of legs = 585, Let the total number of workers= x.
2x + x × 4 + (x+1) 3 + (x+1) 4 = 585....x = 34.
Thus number of workers are 34.
