(c) 2
(d) 4








S1. Ans. (a) 
Sol. 
9x² + 16 y² = 60
3x + 4y = 6 …(1)
Squaring both side on 1
9x² + 16y² + 24xy = 36
60 + 24xy = 36
24xy = – 24
xy =  – 1

S2. Ans. (d)
Sol. 
1 – ((1-√2))/((1-2)) + ((1+√2))/((1-2))
⇒  1 + 1 – √2 – 1 – √2 
⇒ 1– 2√2

S3. Ans. (b) 
Sol. 
2/3 = 0.66
3/5 = 0. 6
11/15 = 0.73
(11/15) > (2/3) > (3⁄5) 

S4. Ans. (b) 
Sol.
 ∛(-2197)×∛(-125)÷∛(27/512)
= –12 × – 5 × (8/3)= 520/3

S5. Ans. (c) 
Sol.
 (25×1600)/400+ (25/200) ×800
=100+100
=200

S6. Ans. (d) 
Sol. 
=(2×2×2×32)/(4×4×4×16)
=1/4 = 0.25

S7. Ans. (c) 
Sol.
√(12+√(12+√(12+ ….......)) )  
factor of 12 = 4×3
 √(12+√(12+√(12+ ….)) ) 
=4

S8. Ans. (d) 
Sol.
= ((0.013)³+(0.007)³)/((0.013)²–0.013×0.007+(0.007)² )
=((0.013 + 0.007)[(0.013)²-0.013×0.007+(0.007)²])/((0.013)²-0.013×0.007+(0.007)² )
= (0.013 + 0.007)
= 0.02

S9. Ans. (b) 
Sol. 
(4-0.2)/(4+0.6)
= 3.8/4.6 
≅ 0.8

S10. Ans. (c)    
Sol.
 (√24+√216)/√96
= (√24+3√24)/(2√24)
= 2
