Sandeep is knitting a 25 cm wide two meter long scarf. It takes him 30 rows of 22 stitches each to knit a 10cm x 10cm trial (“tension square”). How many stitches will he need for each 25cm row in the scarf?

Answer: 55 stitches

The tension square provides the ratio of stitches to length: 22 stitches for 10 cm. To find out how many stitches are needed for a 25 cm row, we can set up a proportion. If 10 cm requires 22 stitches, then 1 cm requires 22/10 = 2.2 stitches. Therefore, for 25 cm, Sandeep will need 2.2 stitches/cm * 25 cm = 55 stitches.

Which image completes the pattern?

Answer: A

This is a visual pattern recognition question. Without the images, the explanation relies on common pattern types. The correct image 'A' would complete the sequence by following a specific rule, such as rotation, addition/subtraction of elements, or a change in color/shape, consistently applied across the preceding images in the pattern.

Which image continues the top sequence?

Answer: C

This is a visual pattern recognition question. Without the images, the explanation relies on common pattern types. The correct image 'C' would continue the sequence by adhering to a consistent logical progression, such as a specific movement, transformation, or alteration of elements from one image to the next.

Which image continues the sequence?

Answer: A

This is a visual pattern recognition question. Without the images, the explanation relies on common pattern types. The correct image 'A' would logically follow the established pattern by demonstrating the next step in a sequence of changes, such as a specific rotation, reflection, or incremental modification of the visual elements.

What is the next number in the series 1, 4, 9, 16, ?

Answer: 25

This number series consists of perfect squares: 1 is 1 squared (1^2), 4 is 2 squared (2^2), 9 is 3 squared (3^2), and 16 is 4 squared (4^2). Following this pattern, the next number in the series will be 5 squared. Therefore, 5 * 5 equals 25.
