ExplanationLet the Oranges be 'O', Bananas be 'B' and Apples be 'A'
From the given data,
2O + 3B + 4A = 15 ...... (I)
3O + 2B + A = 10 ..... (II)

= ?10 x 15
= ?150
= ?25 x 6
= ?25 x ?6
= 5?6
Correct Answer: 19/32
Explanation:
?36.1/102.4
= ?361/1024
= 19/32
Correct Answer: 192
Explanation:
?324/ 1.5 = N / ?256
? 18/1.5 = N/16
? N = (18 x 16) / 1.5 = (18 x 16 x 10) / 15
= 192
Correct Answer: 0.024
Explanation:
Sum of decimal places being equal in Num. and Denom. of given expression
So ,Given expression is equivalent to
?(324 x 81 x 4624) / (15625 x 289 x 729 x 64)
= (18 x 9 x 68) / (125 x 17 x 27 x 8)
= 3/125
= 0.024
Correct Answer: 138.75
Explanation:
Given expression = ?15625 + ?15625/100 + ?15625/10000
= (125 + 125/10 + 125/100)
= (125 + 12.5 + 1.25)
= 138.75
Correct Answer: 0.3
Explanation:
Given expression = ?0.01 + 0.08
=?0.09
= 0.3
Correct Answer: (3 + 2?2)
Explanation:
Exp. = 1 / (?9 - ?8)
= [1 / (?9 - ?8)] x [(?9 + ?8) / (?9 + ?8)]
= (3 + 2?2 ) / (9 - 8)
= (3 + 2?2)
Correct Answer: 0.252
Explanation:
?0.064 = ?0.0640
= ?640/10000
= ?640 / 100
= 25.2/100
= 0.252.
Correct Answer: 15
Explanation:
?176 + ?2401
= ?176 + 49
= ?225 = 15
Correct Answer: 2
Explanation:
(?32 + ?48) / (?8 + ?12)
= (?16 x 2 + ?16 x 3) / (?4 x 2 + ?4 x 3)
= (4?2 + 4?3) / (2?2 + 2?3)
= 4(?2 + ?3) / 2(?2 + ?3 ) = 2
