IV. Solve it

21) 55/100 = 0.55

22) gain% =[ (SP - CP )/CP] × 100%

23) loss = CP - SP = 700 - 658 = 42

24) 3: 5

25) 1980 - 180 = Rs. 1800

26) S.I. = (P× R × T)/100

27) 3/2

28) 2⁵ ( or 2× 2 × 2× 2 × 2)

29) 0.235

30) a^(m-n)

Section - B

31)

CP = 700

SP = 570

lost = CP - SP = 700 - 570 = 130

Lost % =( Loss / CP) × 100 = 130/700 × 100

= 130/7 %

= 1 8.57 %

32)

Interest

=( P × R × T) /100

=( 1800 × 12 × 2 )/100

= 18 × 24

= Rs 432

33)

Anil's percentage

= (375/500) × 100

= 375/5

= 75 %

Sunil's percentage

= 420/600 × 100

= 420/6

= 70 %

Anil's performance is better.

34) (12/100)× 800 = 12 × 8 = 96
