Question
A, B and C joined into a partnership with investment
in the ratio of 6 : 7 : 9 respectively. Behind one year, B doubled his investment. At the end of two years, they gross a profit of Rs. 59500. What will be the portion of B in the entire profit?Solution
let the portion of A, B and C = [6 x 2] : [7x 1 + 14 x 1] : [9 x 2] = 12 : 21 : 18 = 4 : 7 : 6 = A:B:C Let 4+7+6 = 17 total Then 17’s = 59500 given, 1’s = 3500 Than the portion of B will be = 7 x 3500 = Rs 24500
2(3/4) of 2880 + 54% of 7520 - ? = 302
Find the value of the following expression:
372 ÷ 56 × 7 – 5 + 2
- What will come in place of (?), in the given expression.
(5³ + 3²) × 2 = ? (1225/25) - (192/96) + (50/5) = ?

What will come in the place of question mark (?) in the given expression?
(555 + 385 - 535) ÷ 15 X ? = 36 X 30
- What will come in place of (?), in the given expression.
75% of 640 – 20% of 150 = ? `(21 xx 51 + 54)/(9 xx 14 - 30 )` =?
95% of 830 - ? % of 2770 = 650
