1 CP= 100=> MP= 140 ==> SP = 3/4 * MP= 3/4 * 140= 105
==>Profit %= 5%
2. (10*18 + 12*50)/ (50+10)== 780/60= 13
3. given 1:2:3 , also B+C= 9000 ; from ration 5= 9000
==> 1= 1800 =A ; 3= 5400= C
Ans= C-A/A * 100 = 5400-1800/1800*100= 200%
4. 20% work in 25 days ==> 100% work in 125 days
==> 25 days extra required.
5. r=7; h=40 ; CSA= 2*pie * r*h==> 2* 22/7 * 7*40= 1760
6. A=90 so B=100
ans= 100/90 * 100= 111.11%
7. 144+16= 160=40%==> 100%= 160*100/40= 400
8. CND
9. Amount=3/2==>SI=1/2
1/2= 1 * r * 5/100==>r= 10%
10 Avg speed= 2*12*6/ (12+6)= 8kmph
time= 8 hrs; D= 8*8= 64
so Home to office= D/2= 64/2= 32 km
