Solutions

S1. Ans.(c)

Sol.

⇒ Diagonals of a rhombus bisect each other at right angle

In ∆POQ, cos60°=OQ/PQ

⇒1/2=OQ/8⇒OQ=4

∴ QS = 2 × OQ = 4 × 2 = 8 cm

S2. Ans.(b)

Sol. In ∆ABC

∠A + 2y + (180 – 2x) = 180

⇒ ∠A = 2(x -y)..(i)

And,

In ∆BCD, 48° + y + x + (180 – 2x) = 180

⇒ x – y = 48°…(ii)

⇒ from eqn (i) and (ii) we get

∠A = 96

S3. Ans.(d)

Sol. C.P. of article

=Rs.(9300-3100)

=Rs.6200

To gain 25%

S.P. = (6200×125)/100

= Rs. 7750

S4. Ans.(b)

Sol. Interest/Principal=1/10

∴ Rate = (S.I.×100)/(Principal×Time)

=1/10×100/4=2.5% per annum

S5. Ans.(c)

Sol. Amount = P (1+R/100)^T

=2800(1+10/100)^(3/2)

=2800(1+1/10)(1+1/(2×10))

=2800×11/10×21/20=Rs.3234

∴ Compound interest

= Rs. (3234 – 2800) = Rs. 434

S6. Ans.(d)

Sol. 3 men ≡ 8 boys

∴ 2 men + 6 boys

=(2+9/4)men=17/4 men

∴M_1 D_1=17/4×D_2

⇒3×17=17/4×D_2

⇒D_2=(3×4×17)/17=12 days

S7. Ans.(b)

Sol. No. of shoes of Reebok brand

= 23% × 1200 = 276

S8. Ans.(a)

Sol. Difference = 8% × 1200

= 96

S9. Ans.(c)

Sol. Difference is same as 5% in (c).

S10. Ans.(b)

Sol. No. of Puma shoes = 21% × 1200

= 252

No. of Nike shoes = 216

∴ % more =(252-216)/216×100

= 16.67%
