Solution: PT = 45000 P = 36000 T = 1year R = ? we know, PT = P(1+R/100)T or, 45000 = 36000 (1+R/100)1 or, R = 25% so population after 10 years = 36000 ( 1+ 25/100 )10 = 36000 x 9.3132 = .....

Solution: 10mm = 1 cm 1 mm = 1/10 cm 500 mm = 1/10 * 500 cm = 50 cm Again, 1000 mm = 1 m or, 1 mm = 1/1000 m or, 500 mm = 1/1000 * 500 = 0.5 m And, 1000000 mm = 1 km or, 1 mm = 1/1000000 km or, 500 mm = 1/1000000 * 500 = 0.0005 .....
