(a) 6 kg
(b) 8 kg
(c) 12 kg
(d) 10 kg
SOLUTIONS:-
Sol 1. (d) 10x + y – (x + y) = 81
9x = 81, So x = 9
Required numbers are 90, 91, 92, 93… 99.
Sol 2. (c) Let numbers be x and y.
ATQ, x + y = 7a, x – y = a, and xy = 24a
On solving, x = 4a, y = 3a
Hence 24a = 4a*3a. So, a = 2
Required product = 24*2 = 48
Sol 3. (b) LCM of 45, 75 and 90 = 450
So traffic lights will change again at 7min 30sec = 7:27:45 hrs.
Sol 4. (d) L.C.M. of 2, 4, 6, 8, 10, 12 = 120 sec.
Number of times it toll together in 30 minutes = 1800/120 + 1 = 16 times.
Sol 5. (b) L.C.M. of 24, 36, 48 = 144.
So, the three girls will meet at one point in 144 seconds i.e., 2 min 24 sec.
Sol 6. (b) LCM of 20, 28, 32 and 35 = 1120
Required no. = 5834-1120 = 4714.
Sol 7. (a) Product of numbers = 21 × 4641 = 97461
Let the numbers be 21a & 21b.
Then, 21a × 21b = 97461, So, ab = 221.
Now, co-primes with product 221 are (1, 221) and (13, 17).
Hence the suitable pair is (273, 357).
Sol 8. (d) Let the numbers be 13x and 15x.
Then, their L.C.M. = 195x.
So, 195x = 39780 or x = 204.
Required numbers are 2652 and 3060.
Sol 9. (b) Other number = (12 × 336/84) = 48
Sol 10. (d) L.C.M. of 91/6, 65/4 and 56/ 3 =3640
So, 3 persons will again meet after 3640 sec = 1 hr 40 sec.
Sol 11. (c) Let total units be 12
Hence units invested by Raman: Rohit: Raja -= 3:4:5
Sol 12. (d) Let 9: 5 = 9x and 5y
ATQ, 9x + y / 5x + y = 4/3
27x + 3y = 20x + 4y
7x = y, Can’t be determined as cannot be solved further.
Sol 13. (b) Largest size of the tile = H.C.F. of 378 cm and 525 cm = 21 cm.
Sol 14. (c) Rs5: Rs 2: Re 1
Ratio of no. of coins = 4: 6: 9
Total amount= Rs 20: Rs 12: Rs 9
Then ATQ, 41R = 4100, R = 100
Hence, no. of coins of Re 1 = 9R = 900
Sol 15. (a) Initial Copper: Tin = 4:3
Final Copper: Tin = 10:9
Since only Copper is extracted, hence Tin remains same, therefore, (4: 3)*3 = 10: 9
Diff. between ration of copper = 2R,
ATQ, 21R = 63, R = 3
So, 2R = 6 kg copper extracted
