Question
Ravish has read 4/5 of a book while Soma has read only
5/8 of the book she is reading. Both, however, have another 120 pages of their respective books remaining to be read. What fraction of the number of pages read by Ravish has been read by Soma?Solution
Ravish has read 4/5 of a book. The remaining read of Ravish = (1-4/5) = 1/5 Soma has read-only of the book The remaining read of Soma = (1 - 5/8) = 3/8 Now, Total pages in Ravish's book 1/5 = 120 pages = 600 pages Total pages in Soma's book  3/8 = 120 =320 pages Now, The fraction of the number of pages read by Ravish has been read by Soma is (320 x 5/8)/ (600 × 4/5) = 200/480 =5/12
12 % of 72 × 25 – (x ÷ 20) × (16 ÷ 24) × 36 + 1/5 × x = (4 ÷ 12) × 36 ÷ 1/4
√( (664+ √(136+ √(59+ √(21+ √(7+ √81) ) ) ) ) ) = ?
3? x 23 ÷ √ 256 = 40.5
3% of 3000 × ?% of 2000 = 3600
What will come in the place of question mark (?) in the given expression?
? = (40% of 80% of 6400) ÷ 64
53 – 8 = ? + 126
- Simplify the following expression:
(48% of 800 × 3) ÷ 6 + 440 ÷ √25 - 14² (√ 121 x 41) + (3√343 x √289 ) = ? x 19  Â
25% of (?) + (1/4)of 5600 = 2500 – 20% of 1940Â
