ANSWER KEY:-
Q.1. Sol-(C) |2x - 1| + |x - 3| = |2×1 - 1| + |1 - 3|
= 1 + 2 = 3
Q.2. Sol-(C) 3 sinx + 5cosx = 5
on squaring both side/ दोनों ओर वर्ग करने पर
9 sin2 x + 25co2 + 30sinx cosx = 25
9(1-cos2 x) + 25)1-sin2 x) + 30 sinx cosx = 25
9 + 25 - (9cos2 + 25sin2 x - 30 sinx cosx = 25
9 = (3 cosx - 5sinx)2
3 cosx - 5 sinx = 3
Q.3. Sol-(C) Le two number is 29a and 29b
29a + 29b = 232
a + b = 232/29 = 8
(a,b)= (1,7) (3,5)
The pair is (87, 145) (29,203)
Q.4. Sol-(C)
Q.5. Sol-(B) LCM of 22,18 = 198
Cost of 198 mango at the rate of 18 for Rs. 22= 242
Selling price of 198 mangoes at the rate of 22 for Rs 18 = 162
Loss = 242 - 162 = 80
Q.6. Sol-(A) Number must be fector of (34041 - 32506) = 1535
Now, 1535 has only two fector 5 and 307
So, three digit number is 307
Q.7. Sol-(D) Let the train will meet each other after x hours
30x + 27x = 342
⇒ 57x = 342
Q.8. Sol-(C)
Q.9. Sol-(A)
Q.10. Sol-(A) 13 + 23 + ........103 = 3025
4 + 32 + 108 + ...... + 4000
4(1+8+27 .....+1000)
4(1+23 +33 ......103)
4 × 3025 = 12100
