Dear Student, Let the number of cattles be xNumber of cattles drowned in flood= 10% of x=10100×x=0 1xRemaining cattles=x-0 1x=0 9xCattles died of disease=20% of 0 9x=20100×0 9x=0 2×0 9x=0 18xRemaining cattles=0 9x-0 18x=0 72xNumber of cattles lost=5% of 0 72x=5100×0 72x=0 05×0 72x=0 036xCattles remaining=0 72x-0 036x=0 684xAs we know total number of cattlesremaining=1368Hence 0 684x=1368⇒x=13680 684⇒x=1368×1000684⇒x=2000Hence total 2000 cattles were there Regards,

q19 plz solve

Dear Student,

L e t t h e n u m b e r o f c a t t l e s b e x N u m b e r o f c a t t l e s d r o w n e d i n f l o o d = 10 % o f x = \frac{10}{100} \times x = 0.1 x R e m a i n i n g c a t t l e s = x - 0.1 x = 0.9 x C a t t l e s d i e d o f d i s e a s e = 20 % o f 0.9 x = \frac{20}{100} \times 0.9 x = 0.2 \times 0.9 x = 0.18 x R e m a i n i n g c a t t l e s = 0.9 x - 0.18 x = 0.72 x N u m b e r o f c a t t l e s l o s t = 5 % o f 0.72 x = \frac{5}{100} \times 0.72 x = 0.05 \times 0.72 x = 0.036 x C a t t l e s r e m a i n i n g = 0.72 x - 0.036 x = 0.684 x A s w e k n o w t o t a l n u m b e r o f c a t t l e s r e m a i n i n g = 1368 H e n c e 0.684 x = 1368 \Rightarrow x = \frac{1368}{0.684} \Rightarrow x = \frac{1368 \times 1000}{684} \Rightarrow x = 2000 H e n c e t o t a l 2000 c a t t l e s w e r e t h e r e .
