Question

1. Increase:
(i) 80 by 25%
(iii) 710 by 15%
(ii) 820 by 30 percent
(iv) 9o by 100 percent​

Answer 1

Answer:

I) first let us find out 25 percent of 80

25 / 100 * 80

= 1/4 *80

= 20

So, 80 increased by 25% is

20+80

= 100

ii) 15% of 710

= 15/100*710

= 15/10*71

= 1.5*71

=106.5

So,

710+106.5

816.5

iii) 30% of 820

= 30/100 * 820

= 3*82

= 246

So,

= 820+246

= 1066

iv) 100% of 90

= 100/100*90

=90

So,

90+90

= 180
