Let C = 100 So B = 20% less than C or 80% of C = 80/100×100 = 80 And A exceeds B by 40% So A = B + 40% of B = 80 + 80 × 40/100 = 112 So A : C = A/C = 112/100 = 28/25
Let original price of sugar=Rs.100 Increased price=20/100×100+20=Rs.120 Difference=Rs.20 Required %age=20/120×100=16.6%
70% are student girl so,30% student are boys so, 30%=510 so, total no. of students in school =100% 30%=510 so,100%=510×100/30=1700 so, total no. of students in school is 1700
sum = x. amount =7x/6. S.I. =(7x/6 – x) = x/6 ; time = 3 years Rate =[ (100 * x) / (x * 6 * 3)]% = 5.5%
